I have some wild bets for at least (x10, x15)
OST (12 mil. market cap)
WaBi (9 mil. market cap)
Bluzelle (23 mil market cap)

But OST is the most likely one for me, main motivators:
the work they have done so far (mainnet, alpha phase 100+ projects n their platform, staking protocols),
partners who will tokenize on OST platform (Usplash, Passkit, Hornet, etc),
no hype marketing (no price talks, no announcements of announcement, no stupid retweet campaigns),


Disclaimer: I'm 30% in OST, and thanks to the steady decline of the market I'm barely even.
