do you think only Bnb, and ethereum altcoin have potential? I don't think so, friends, of course there are lots of altcoins that have potential right now. and even some time ago there was a collapse like Matic and cardano, and that in my opinion is an altcoin that also has potential.
You might have a different opinion but the top ten or the top five have always been the closest to being safe assets as to bitcoin. Going by that ETH and BNB can be given a try if you are having funds to invest in. A load of altcoins are available on the market and you are free to choose from them but since the ETH project has been here for sometime and BNB has been a successful exchange their tokens are in the top, I would add LTC to the list if I could too, because that has also been a resilient project.
Every month does not specifically mean the month of a new altcoin, the same old ones will profit like they did, you have to get into them.
