The most popular ones that has the lowest fee for me are these:
Well, Ethereum is a popular Altcoin and the price isn't high so it's easy to get.
he also has great potential and he can get big benefits, the three coins you mentioned have good abilities and they can grow better so he has the opportunity and you choose him.
After everyone saw the peak for ethereum, we are all determined that it's likely to be at the top again. Dogecoin is a known coin for being a meme coin but it has a good feature because it has a very low fee. And for Nano, I don't hold this coin but I've read that it has no fee so I think that's a good candidate for op's search.
