Which alt coin you think can reach $10k in 2020 which is below $1k now
IMO, Ethereum and Dash can.
Only those, forget about monero, litecoin, and all those little altcoins because they are not going to reach more than $1,000 at least.
Dash and eth can do it.. For me, ethereum will reach that price before Dash, this is just because of common sense of course.
