We all know how temperamental the market can be but do you think this is just a short term spike?
If you are dead serious about gaining a profit on bitcoin, You must hold your ground and just get back on your bitcoin next year or so.
Not only bitcoin but most of the coins are falling down when the bitcoin price goes down, at this stage if you can predict the price then the best way to cover the loss is to move to Tether (USDT) or to any fiat money, wait for the crash(es) and then invest back in crypto which in this case you can increase the volume of that coin. But this method does not always work as you can sell a low rate, have less fiat/usdt and then to buy back the coin could cost more expensive and you can fall in loss. My suggestion is if you haven't sold yet the coins then hold as I'm doing.
