There are a lot of promising altcoins that you can invest in, and will make huge returns, you just have to be willing to do your research. If you continue to ask people, they will just shill their own coins for you. It's better you do your own research.
I will advise you to research some altcoins that did very well during the previous bullrun but their prices are presently low now because of the bear market. And you should invest in them, they will go high than their all time high at the top of the market.
I have made this mistake on investing on coin based on opinions and it has really not favored me, I realize that many people are not genuine in their opinions; they just say shill these coins without them understanding the future of the coin, so I do research personally on these coins no matter the review that they get.
For the altcoins that has previously performed, do you think they still got any chance to make it during the bull run again, because it seems to me like all these old projects are already giving up for the newer projects, so many old coins that I have and I have not seen them respond to the movement of bitcoin.
