I have a few altcoin and I wanted to know which is the best investment option where I can invest my altcoin and earn some profits as their is no point of just holding them and let them stay dead in my wallet.
In my opinion, the best way to invest in altcoins is to translate them into the most stable cryptocurrency such as Bitcoin or Ethereum and long-term hold it. If you want to put your own coins on a deposit then I have not heard about it and most likely it is some kind of deception. Be careful with hereby.
