I want you to comment on this scenario, when should one cash out, as the volitality of the market is very scary.
What's your advice? Is it keep holding? What if keep holding means holding at a loss?
It will depend on what are your plans. Before buying, you must've a set of plans that you will do if the best or the worst happens.
Holding at a loss is ok for me as long as it is Bitcoin or Ethereum. For some reasons, I find these 2 coins trustworthy enough that if it goes down I believe that it will go up again someday so I just hold it even I'm still at a loss and after all it is just a paper loss unless you sell it really at a loss then you really lose your money.
Planning, knowing the support and target price to buy and sell will help you.
