Price dump, It's our wrong thought. When market dump every coin price is dumped Bitcoin or altcoins. From altcoins you could get most good profits, check last year pump % of Bitcoin and altcoins.
in 2019 I bet on bitcoin against altcoins, the old rules don't always work. it is better to look at the essence of many altcoins is just garbage.
Bitcoin remains one of the best in Cryptocurrency. with the development of owned Bitcoin experience increased will increasingly bring it into valuable coins and coins become so profitable. so the Bitcoin is still the coin of the trust and become the best coins.
