You should invest in bitcoin instead in altcoins because bitcoin is more reliable to invest since they are operating in the industry for a long period of time and they are the number one company as well.
For me Bitcoin is always a better choice because the value of bitcoin always increases over time, the development of bitcoin just started, it is still possible to continue more developed in the future. However, in the present time, when the price of bitcoin is not too much volatility, altcoin is still the better choice because investors and traders will focus more on altcoin, altcoin will often receive a lot of strong pumping, and the profit we can get is amazing.
