Wonder how the weighting will work. If you don't massively overweight smaller coins, you'd just end up holding like 80% Bitcoin & Ethereum with very little of anything else.
Bitcoin cash comes in at #7 on coinmarket cap and while I wouldn't call it a scam, it's not a respectable project IMO. And it quickly gets worse from there over the next 10.
Strongly agree that the best bucket is going to be composed of a vast majority of bitcoin and ethereum.
I don't believe crypto is on the whole in a bubble right now but the fact that Bitcoin Cash has a market cap of >$5B is one of the biggest things that makes me question that.
I think BCH is a reasonable idea, block size is a problem with BTC and increasing it is fine even if it makes it less likely that normal users will run full nodes.
The scumminess of it comes from people like Roger Ver who peddle it as the "true" BTC. e.g., bitcoin.com is owned by the BCH folks and they have several intentionally misleading things there that try to re-brand BCH as BTC and BTC as BTC legacy or whatever.
It's a good time to write a crypto whitepaper and put up a fancy website. It's not alt-season yet .. when it starts is when you see the real shitcoin proliferation. Wouldn't be surprised if the number is in the 1000s.
I would assume you'd go by the market cap and trading volume of different coins. So BTC and ETH would dominate, but you'd also have to make room for LINK, XRP, DOT, etc.
