Don't believe in all coins where many shit coins everywhere. Yes you may gainer from one coin but this is not mean all coins will behave same like this.Before your investment you must have to more clear for this coins roadmap and mission so that no upset will run you.
Like the saying is life is about risk even with meme coin you can hit it big and exit. All we have to do is be careful but too much of smartness don't allow for risk taking. However we need investment in top coins and not coins that are yet to go into exchange. Some investors still believe in putting money in ICO but that failed so many. That is to invest in what you don't see the prospect is the problem of diversification.
