In no particular order:
Decline of day traders and frequent "shorters" who just got burnt bad will reduce overall crypto volatility.
Altcoin to true Fiat pairing.
Alts will separate from BTC and not be in lock-step.
Crypto may actually become a true store of value during the next recession (which is long overdue, but OP pegs as happening in 2-3 years).
Legitimization of ICO funding in SK, JPN, USA through regulatory bodies.
Regulation and reduction in volatility will reduce illegal activities.
