Bitcoin and other cryptocurrencies value fluctuate more in the market and all the time bitcoin value grow again and again after the dump we see in the meanwhile time.
However you please do the changes in the investment side for picking the right coins.
If we are mentioning at the present, yep I completely agree that bitcoin is most dominant coin in the market and actually it’s great difficult for any coin to take over this BIG COIN. Honestly bitcoin is most dominant both about demand, supply, and a very impressive price. Almost all people focus on bitcoin more than any other coins, even I just focus on the bitcoin price and then making a prediction for another coin like altcoins. Generally, if you want to live at the crypto market for a long time, I advise you to collect some bitcoin.
