Actually all the scams have now been weeded out - at least from the top 30 or so rankings, bar 2 or 3 floaters. Also BTC is at one of its dominance peaks so we're staring down the face of the next altcoin "munch" into BTC's dominance.

The more time goes on, the less distinction there is between the "first" and the 2nd, 3rd, 4th etc. Also BTC has planted is flag where utility "isn't" which means it's zip-all use for actual everyday use. Fine if you want to park it till retirement but forget anything else. (Including LN off-chain "coin loss" service).

Not many people made money by sitting on their BTC and keeping it warm to the exclusion of anything else and they're gonna make even less from now on. I expect dominance to stabilise around 20%-30% eventually (if not less) as utility starts to dominate long term store of value in the crypto ecosystem.
