I prefer to look in to high cap altcoin that really solved of the current problem in crypto market. One of the problem in the market now is low TPS, low fenalty time and high fee of transaction, and some good high cap coin that solved that is XRP IOTA, SOL, and ADA AVAX.
I would not select XRP. XRP is based on a centralized database, controlled by Ripple Labs. It is completely different from truly decentralized and censorship resistant coins. Technically, Ripple is very outdated and against decentralized distribution.
I would also not select ADA. ADA has tried to develop DeFi applications for almost 4 years and hasn't still figured out how to enable it safely. Big red flag.
But I can agree to SOL. It seems to be an innovative approach but now, experts need to review it.
I would replace XRP and ADA and select IOTA and AVAX instead. AVAX has proven to be a fully functional platform where a great team from Cornell University, US, has developed a new tech and IOTA, a project backed by German industries is making huge progress from Pollen and Chrysalis.
