I find that it is very dangerous when you buy crypto under the top 100, because those cryptos will not be guaranteed by the crypto in the top 100. so I think you should buy cryptos that in the top 100, beside Bitcoin there is a lot of potential cryptos.
Many of the coins in the top 100 give not a guarantee either that you are going to get profits, in fact if you check out the coins that were at the top of the market a few years ago you will find that most of them have disappeared that is why the only coin that I am sure is going to be here for a long time and that I am willing to hold is bitcoin, every other coin is a coin in which I do not trust as much as I trust in bitcoin.
