SOL and ADA. SOL has been pumped so hard so most people were against the idea to buy it or look forward to its next bull run but I think this coin still has a lot of room to grow and many NFT coins going to flock over its network pretty soon. For ADA well I think the inactive for its in this year so there might be a chance it was overlooked look and I'm waiting for its pump at the next bull run.
Well, why did ADA grow well this year, I think the holders were very happy (those who waited), and even now there is still a good potential.
I disagree with you about SOL, but ADA is a very good option.
Not really sure about ADA, as it was because it never show such significant market growth this year and I'd never think he can perform so well just like 2017. If I do hold some altcoins, ADA is probably not on my list, I'd rather have to choose those hot coins and high trading value. That of course, BTC is on the top and followed by BNB, ETH, and I may take some consideration to SOL and Axie (NFT). Well, I guess, I shouldn't have to buy more coins this time as the rally has started already.
