A Look at Two Crypto Presales in 2025

2025/11/04 01:26

A $435 million presale sounds exciting—until you realize there’s no product behind it yet. That’s the story with BlockDAG (BDAG), the token everyone’s talking about. It’s raised huge money and promises next-generation blockchain tech, but investors haven’t seen anything live.   

In contrast, Digitap ($TAP) is already working in the real world. The app is live on both Apple and Google Play, complete with a Visa card, real users, and a growing economy powered by its crypto presale. One project is selling potential. The other is already proving it.

BlockDAG: The Hype Machine Behind a $435M Presale

BlockDAG is one of the biggest talking points of 2025. It is a Layer-1 blockchain using a Directed Acyclic Graph (DAG) structure instead of the usual chain model. That setup allows faster transactions and lower fees. The presale token price sits around $0.005, and investors have poured in around $435 million.

It’s a bold pitch—but for now, everything remains in the presale stage. There’s no mainnet, no ecosystem, and no proof that the network works as promised. The website highlights future goals: mining apps, smart contracts, and developer tools. But investors are still buying into an idea, not a product.

Projects that raise hundreds of millions before launch often face high expectations. Some never deliver. With so much money already in, the chance for early buyers to see major returns becomes smaller. That’s why more investors are looking at projects that already show results before launch.

Digitap: The Omni-Bank That Brings Crypto Into Everyday Life

A borderless economy is emerging—where dollars, euros, and crypto move freely without delay or cost. Payments clear in seconds, and anyone can hold cash and digital assets in one secure account. That future is no longer a concept. It’s already working inside Digitap.

Digitap is the world’s first omni-bank—an app that connects crypto and cash in one place. It’s already live and available to download on both the Apple App Store and Google Play Store. Users can open accounts, send money, and spend instantly with the Digitap Visa card. 

What makes Digitap stand out from typical presales is that the app already works. Users can hold crypto and fiat together, pay globally, and transfer money in seconds. It’s simple to use yet powerful enough for business users who need multi-currency access.

Security is another key focus. The platform has already been reviewed by Solidproof and Coinsult, two well-known blockchain auditors. Every transaction runs through strong encryption and multi-signature wallets. Users can also choose extra privacy through offshore accounts, and smaller balances don’t require full KYC — a rare mix of safety and freedom.

For anyone looking for the best crypto to buy that offers real utility instead of promises, Digitap delivers something tangible.

$TAP Crypto Presale Moves Fast as Early Buyers Rush In

Digitap’s crypto presale has already raised over $1.3 million, which shows strong interest from early investors. The current price of $TAP is $0.0268, moving to $0.0297 in the next round before a $0.14 launch. Early participants gain from each price step before listings on major exchanges.

The token follows simple, transparent rules. There’s a fixed supply of 2 billion $TAP, with no inflation, no hidden taxes, and no surprise emissions. Half of all platform profits are used for buybacks and token burns, which reduces supply and supports long-term value growth.

Staking adds another incentive. Early holders can earn up to 124% APR during the presale, and up to 100% APR after launch, from a fixed pool rather than inflationary rewards. The system rewards loyalty while keeping the token’s scarcity intact.

What Is the Best Crypto Presale in 2025?

The difference between Digitap and BlockDAG is clear. BlockDAG has hype and big numbers. Digitap has a product, users, and results. One is raising funds to build; the other has already built.

Digitap’s edge lies in its readiness. The app is live, audited, and fully functional. It already solves everyday financial problems—fast global transfers, low fees, privacy, and easy crypto spending. Its deflationary token model and live Visa card show that this isn’t another concept on paper—it’s a working system.

BlockDAG may have $435 million in hype. Digitap has real users, real spending, and a real app. That’s what makes $TAP the smarter move in today’s crypto presale market.

Preliminary analysis of the Balancer V2 attack, which resulted in a loss of $120 million.

Preliminary analysis of the Balancer V2 attack, which resulted in a loss of $120 million.

On November 3, the Balancer V2 protocol and its fork projects were attacked on multiple chains, resulting in a serious loss of more than $120 million. BlockSec issued an early warning at the first opportunity [1] and gave a preliminary analysis conclusion [2]. This was a highly complex attack. Our preliminary analysis showed that the root cause was that the attacker manipulated the invariant, thereby distorting the calculation of the price of BPT (Balancer Pool Token) -- that is, the LP token of Balancer Pool -- so that it could profit in a stable pool through a batchSwap operation. Background Information 1. Scaling and Rounding To standardize the decimal places of different tokens, the Balancer contract will: upscale: Upscales the balance and amount to a uniform internal precision before performing the calculation; downscale: Reduces the result to its original precision and performs directional rounding (e.g., inputs are usually rounded up to ensure the pool is not under-filled; output paths are often truncated downwards). Conclusion: Within the same transaction, the asymmetrical rounding direction used in different stages can lead to a systematic slight deviation when executed repeatedly in very small steps. 2. Prices of D and BPT The Balancer V2 protocol’s Composable Stable Pool[3] and the fork protocol were affected by this attack. Stable Pool is used for assets that are expected to maintain a close 1:1 exchange ratio (or be exchanged at a known exchange rate), allowing large exchanges without causing significant price shocks, thereby greatly improving the efficiency of capital utilization between similar or related assets. The pool uses the Stable Math (a Curve-based StableSwap model), where the invariant D represents the pool's "virtual total value". The approximate price of BPT (Pool's LP Token) is: The formula above shows that if D is made smaller on paper (even if no funds are actually withdrawn), the price of BPT will be cheaper. BTP represents the pool share and is used to calculate how many pool reserves can be obtained when withdrawing liquidity. Therefore, if an attacker can obtain more BPT, they can profit when withdrawing liquidity. Attack Analysis Taking an attack transaction on Arbitrum as an example, the batchSwap operation can be divided into three stages: Phase 1: The attacker redeems BPT for the underlying asset to precisely adjust the balance of one of the tokens (cbETH) to a critical point (amount = 9) for rounding. This step sets the stage for the precision loss in the next phase. Phase Two: The attacker uses a carefully crafted quantity (= 8) to swap between another underlying asset (wstETH) and cbETH. Due to rounding down when scaling the token quantity, the calculated Δx is slightly smaller (from 8.918 to 8), causing Δy to be underestimated and the invariant D (derived from Curve's StableSwap model) to be smaller. Since BPT price = D / totalSupply, the BPT price is artificially suppressed. Phase 3: The attackers reverse-swap the underlying assets back to BPT, restoring the balance within the pool while profiting from the depressed price of BPT—acquiring more BPT tokens. Finally, the attacker used another profitable transaction to withdraw liquidity, thereby using the extra BPT to acquire other underlying assets (cbETH and wstETH) in the Pool and thus profit.
