Sell everything is not a good idea. I prefer to think about it and then take the decision.
and I think it's not a good idea. No need to go to extremes. You should always think about the future and how to live now
If you think about the future, you should buy some bitcoins. It will rise in value in the long term .
Yes that is needed if you can see that bitcoin will rise in the future and have all the potential to pump. So while the price is still that not satisfying you should not be selling the bitcoins you have, you may your alt coins for profiting with bitcoin but don't ever sell your bitcoins. Just be patient and wait for the right time with the right price.
correct all possible future bitcoin is going up after the mining berahir, for now the price of the bitcoin is unstable, it is better to now save the bitcoin you have and sell some only
