Just wondering, why only BTC and ETH? Few altcoin such as BNB and ADA are currently popular and have high market cap.
Are BNB and ADA going to be around in 5 years time though and if they are are they going to be actively developed or worth anything? The thing with any altcoin is you do not know how good the development team is and how trustworthy the people are behind the coin and most like I would say over 95% of altcoins fail within a couple of years and its usually because of no active development or the team behind it decided to scam.
Fair point, i was assuming you focus on market cap in last few years. ADA have weekly technical update, although AFAIK it's not very transparent. BNB is only popular because it's owned by Binance. Another altcoin such as Monero still have active development with good transparancy.
