Comparing to last bullish on 2017-2018 back then looks like current bullish was really giving some good exposure to the global market, The total Known Altcoin doubled with only 3 Years span and this was really good for the crypto market even though some of altcoin out there just an Pump & Dump Scheme or another exit scam but we can also see some good altcoin with Real use case out there Especially last 2 Years with DeFi, NFT, Decentralized Storage, CDN, etc. Well, Let's hope the quantity & quality will increase in the future!
