yes bitcoin is really good invest now because its price is expecting to raise high in next few months, some people are even expecting that the price of bitcoin can cross the all time high price this time. therefore to me it is the best investment in present time.
I don't know if it's the best investiment, but it's an easy investiment for sure, anyone can do it very easily and you don't need to have big amounts of money to start or banks bureucracy. You just need to buy and wait some time to see the BTC rise a bit more and make your profit.
There are another good investiments, but they are more complex, so BTC is very recommended for who wants to invest and doesn't have much to start.
