Ming coins is good but I would than hold it for a longer time and than sell it on a time because most likely that will be more profitable.
It does not have to be long terms but just a bit longer than normal due to the big market that is going up and down.
I think its better to buy them and save them till the end of the year and if that point price reaches to your desired level then you can sell them and if not then you can hold them even longer.
If you think the bitcoin price will rise in the next few years or even decades, it is better not to sell them so soon.
