It is not a new thing that buying bitcoin for a long term is the key success for an investors who has the understanding of bitcoin investment. And the subject makes.it clear for everyone here. It is to buy and it is to sell. In investment you buy and keep it for the period not time which is still low and once it is up to the time you will like to sell them you sell it and take your profits and this is the time of selling. Even if not all it is better to taste the $99k to the $100k then continue again for another All Time High for a long term investment. Investment should be on stages. And I think this is one of the stages to sell. Though it is not for all but those who like to.
