I have never invested in a solana project directly. but I made quite a fortune from joining the airdrop on a project built on the solana network a few months ago, like Rope. op is lucky enough to profit from those projects, moreover solana is also in hype. although so far I haven't seen the previous project last long, it's still like a pump and dump. or is this just my feeling?
If there is no development afterwards, then high likely that it is just pump and dump coin. Be careful touching this kind of project because the ROI that you are seeing right now may be high, but, for how long? If there will be no actual developments, better get out while you are still in profit. Don't wait too long because you may regret it.
