We can observed in the price history of bitcoin that it keep rising and falling repeatedly. Thus we can say that history is keep repeating itself and I believed that buying bitcoin is still profitable in the long run. But for better return of investment, altcoin is the better choice.
bitcoin is indeed the choice for the long term, but the question and the problem of how to anticipate or makae our money keep running while in bitcoin takes a long time, whereas we cannot delay the need, bitcoin is increased and sometimes it also decreases we can see from the graph above this does occur from year to year
