I don't strongly recommend a project for everyone to buy coins But some who think it's okay will say so Binance recently airdropped BREV with BNB Holder. I haven't sold it yet. Use BNB to subscribe for capital preservation and earn coins, or earn coins on the chain Everyone has obtained this airdrop Let's talk about this coin 1/Not a pure air coin BREV is strongly tied to the business, and when using proof services, it needs to be used for settlement, and when using a prover, it also needs to be pledged As long as the business volume increases in the future, there will be demand for coins. Observing the business can lead to speculation 2/The task is very clear Perform off chain computation and on chain verification to solve the problem of on chain computation not being able to move This requirement is quite common in DeFi, data, and privacy applications, and belongs to tool based infrastructure 3/See if it's possible to convert empty coins into business coins The most common outcome of empty coin trading is that everyone sells it as soon as they receive it, and the rise and fall depend entirely on emotions I'll take BREV a little longer to see if there's any continuous business data behind it 4) Airdrop space for observing high cost-effectiveness This part was originally an additional income It's not a position bought by chasing after high prices For me, it is more suitable for mid-term observation: If given the opportunity, take a trend If you don't have a chance to rebound, leave without being kidnapped by emotions 5/The signals I can monitor are very specific I mainly look at two things: Has there been an increase in the number of proof tasks and proof fees Has the scale of pledge increased If these two can break the trend, I will continue to take them If you can't come out, then follow the empty coin insertion logic and release them in batches when there is a rebound I'm not mindless either What I am more afraid of is the selling pressure caused by unlocking and adding circulation later on So I won't end up in dire straits My way of handling it is: Suddenly skyrocketing but the on chain data did not keep up, it was seen as an emotional boost and sold in batches The synchronous strengthening of data and pledge is why we are considering keeping a portion of the mid-term investment Additionally, holding BNB as a passive means of earning money is indeed enjoyable BNB https://www.
