I dont think it is the right time for altcoin. I observe that when the value of bitcoin rises, the value of altcoin will fall down. So if there are a lot of demands in bitcoin, expect lower demand in altcoin. So it will be hard for everyone if we just put our investment in one. Its better if we hold bitcoin and also altcoin. But be careful on what coin your going to invest. Because there are many scamm came out.
