I think its very healthy to be sceptical towards any investment. Im currently very sceptical towards the recent boom in crypto land.
But you should benchmark different projects next to each other. Not buying EOS would make sense if you are not believing they will make their promises. But buying and later selling on in a panic is completely irrational to me.
But ok everybody has a different strategy :)
Its very easy to me. Its a gamble this investment but so far there are no fundamentals showing any issues with the project itself.
Probably its noticeable im quite frustrated with the markets :)
