With the recent changes in BTC price, altcoin is getting weaker against BTC, so, this is a good time to pick and fill the bag. Another important part is, after BTC bullrun, once BTC get stable, altcoin follow the bullish trend.
Is it right decision to pick some more altcoin?
Its a good idea, because this time ALTS are down, and i think its a good time to buy more good ALTS, dont wait for too long, because we dont know yet what will happen, maybe in the short period of time, prices may go higher after this BTC bullrun this time, but we could not really predict what will happen in the future, just invest what you can afford to lose and or pick only the best performing ALTS, as there so many ALTS in the market, which are not really performing well.
