Of course, for a long time, it will be very good to hold Bitcoin.The price of bitcoin continue is rising are decreasing.So trading will not be very good for a short time.So if you can hold it for a long time then there is the possibility of double profit.If you want to profit, buy Bitcoin right now and hold it for a long time for your bright future.

This is contradiction, if price is going up and down all the time it can only mean that it is better to go short.

of course there will be more and more altcoins which are faster, cheaper and greater than BTC. But BTC likes a Gold of crypto world. many people trust in its value and no thing can change it. So, in long term, BTC is still the best coin of the world

That is problem with altcoins. There will always be more altcoins, bitcoin will remain only one.
