yes maybe not everything is like that! everything needs a process, but the fact is like that.
sometimes I think, what's the use of them making their own cryptocurrency but when entering the market there is no further price development. after that it feels like dead!
I hope I don't misjudge.
Your assessment is correct that many people make their own coins but after completion there are no developments at all. As if the coin was made only to commit fraud against investors. Anything can happen so we must be careful in investing. But not all coins like that and of course they also require a long process.
