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.
Monero is the coin that will go totally mental.. it is so not user friendly at the moment.. it is so so far from mainstream.. yet it is the best privacy coin hands down..
XMR has the biggest upside out of all the top 20 coins.
