Bitcoin is the first choice of all the people, but some time when the rice of bitcoin become stable or there are chances of dumping bitcoin price then people covert their investment from bitcoin to other crypto currencies, but still when they realize that the price is again getting increasing they reinvest their money in bitcoin for making good profit
Currently investing in Bitcoin is still the safest and most effective way of investing in the cryptocurrency market. Research and analyze new coins to invest and get bigger profits, but leave some of your assets on Bitcoin because it is a very good backup.
