Selling all your coins today is not a good decision because the price of bitcoins is down to $8k dollar and if you are not patient enough to wait then you will just lose a huge amount of profit because bitcoins is expected to reach $50k dollar before the year 2018 ends.
Expected by who?
Sounds like bullshit to me, 6 months for a $42k price spike based on what?
Nothing has fundamentally changed in
BTC to justify it so your just relying on several manipulated pump and dumps.
Everything is possible to happen, who knows ? Maybe it will reach it. But i suggest to everyone do not expecting too much on what will be the price of bitcoin because maybe you will disappointed if it's still around in $7K to $8K.
