Basically, this is a Telegram game where users complete tasks and receive BLUM tokens as a reward. The developers state that in addition to the game component, the project will include its own decentralized exchange (DEX).
As for its prospects, the declared price in the range of $0.50-1.00 looks typical for similar projects at the start. However, this is another tap-to-earn game. They promise a DEX, but it's not there yet, it's all just talk so far. I have seen similar projects come and go, and the scenario is usually the same: the price takes off at the listing because of the hype, then it dies down when the initial interest fades. And this can happen very quickly.
As for earnings, technically you can make some money if you manage to enter early and get out at the top. But let's face it: this is not an investment, it's just speculation. And most importantly, it’s the price paid for your time. People spend hours, days, weeks and months to get bonuses in the hope of getting "free" tokens, but in fact it's not free as you pay with your time, which you could spend on your development.
Strictly speaking, BLUM is not a scam. It’s an honest exchange: your time and attention are exchanged for tokens. But you need to understand that most of these projects are very short-lived. After the decline in trading volumes on centralized exchanges, DEX is unlikely to save the situation, since nobody needs a dying game token.
