there have many coins but we should choose good coin and invest on that, then my suggestion is now you could invest your 1200$ on ethereum because it is now very cheap, then one day ethereum price will bit bitcoin price.
ETH is very risky now, but if we persistently hold them for a long time they will make a profit for us, but mostly you have the patience to hold or not, in my opinion. Do not wait too long, now invest in altcoin will be better. Fast is more profitable for you and me
