as we are seeing other coin such as litecoin ,monera,etherium , are faster in transaction than btc
Bitcoin compared to previous years is very well strengthened, the fact that his jump was up to 3000, I think the current drawdown . this is a temporary phenomenon , and further Bitcoin will only grow.
Bitcoin is the strongest because it is the most popular and is the standard price of altcoins, in my opinion it's hard for any coin to replace bitcoin in a short time, but I hope the influence of bitcoin is not so strong that it makes the market better.
