As Bitcoin keep climbing and altcoin keeps going down, is it better to invest in bitcoin or altcoin now?
I think both options are good for investment. but, for now you can invest into bitcoin when the price still increasing. and you can sell it back when the price starts to stabilize. for altcoin; you can invest in altcoin when the bitcoin price is stable, because when the bitcoin price is stable, the altcoin price will start to increase.
