There will always be a perfect time for everything, even here in the world of cryptocurrencies. The very bullish Bitcoin rally will be unforgiving to the altcoins. That is reasonable as people would definitely dump their altcoins to enjoy the Bitcoin ride. But altcoins will be their option after Bitcoin will reach its highest point. But as of now, it looks like everything is in blood, both Bitcoin and altcoins.
I believe there will be a good moment for altcoin. bitcoin must be more stable first, and that's the time when bitcoin trading will decline and start switching to altcoin. if that happens the altcoin pump will begin.
