My humble predictions.
Interesting, thank you for your opinion. It would be a nightmare if there were 3000 coins, already is with 300
Just a remark on privacy oriented coins, if centralized exchanges force them to leave due to regulations, they can end up on decentralized exchanges, so the market cap can still be calculated based on their prices on those exchanges.
I think we'll make up for 10x the amount of coins by seeing 100x the amount of money flowing in.
True, I didn't mean they would be worth less but they may no longer make top 10. Just that they may fall under a different category - not necessarily underground, but lacking the protectionism, regulation, insurance, legalities & taxation that will probably hit us sooner or later. I'm not
for centralization/regulation myself, but when crypto. takes off it will be the centralized/regulated cryptos that have the massive market caps.
