Normally, the price will fall in the TGE no matter how good the project is especially if the project have an airdrop and distribute the rewards to participants before the TGE. So the best thing to do is to sell some of your holdings if you think the project is good, even the investors will do the same. If the project was really promising, later on after most of the tokens from hunters sold the price will start to increase. That is the fact in the TGE that I've noticed.
Yes, of course, as usual, the price will immediately drop. And every decision will definitely have its own risks.
When deciding to sell everything at the beginning, it means that the airdrop results have become money and this is clearly in hand, if it will drop immediately, then the advantage is that we have already got the money, no matter how much, but the downside is if the coin turns out to be able to skyrocket, so you have to be prepared for this kind of situation.
On the other hand, if you have to hold the coin, it will also be very risky because it could be that it will immediately drop and not be worth anything at all, in fact we won't get even a little from the airdrop results.
Then the last one is to sell some, at least we have got the money in hand, and the rest is just surrender while watching the development. if it's good, the result will be out of the ordinary, if it's bad, the result will be burned. so, it depends on how we expect it to be, what is certain is that most projects will usually fall, especially when the meme project has large airdrops.
