of the three coins available, it seems that for NEM and PIVX, there is no visible progress that could lead to improvement. which is currently all the altcoins are experiencing it, but they are unable to reach ATH as opposed to Solana (SOL) which has hit ATH $ 49.67 - May 01, 2021.
So it could be that during the current alt season, which is still quite a long time, there will be changes if there is really hard work from their management to make improvements. but SOL is very good to be an alternative for joint investment with altcoins, which are also developing well at this time.
