I've been through something like this. It is very difficult to accept and feel the stress. If you stop, then you really lose. Not a matter of money loss, but it is important to learn from failure.
I do not stop and pick another coin and focus on BEF.

Without loss we'll not know where our mistakes in trading. Whether the undercooked analysis factor is in a hurry to decide whether to sell or buy, or because our emotional factors are less stable then maybe because we dont understand money management in trading. Learn the mistakes and keep on trading.
