Remember Risto's probability case( I think we were ~30 cents at the time
) for each of: $3 $30 $300 $3000 ?
I always thought his estimates were pessimistic. My estimates proved pessimistic as well, but his more so. Crypto always surprises me with the scale of it's momentum, and of it's volatility.
I would suspect that we are in for another 10x somewhere in the next year. What then?
By 2022 the mining flow will be a tenth of what it is now, so if the incremental demand remains unchanged in value, a 10x in that time is a given. Any more rapid increase would require accelerated demand. That could come from market adoption, from crypto sector popularity, from diversification flows within crypto, from adverse events in comparables, from technical advances, ... Or any one or more of dozens of other causes.
Given the degree of skepticism in alts, after further consideration, I doubt that multisig etc is fully priced in. This is a very show-me environment. It's advent won't affect the true believers, but the majority of potential reserve demand sources will not be convinced until it is working on mainnet. "Sell the news" does not seem to work so well in alts.
