Of course mentality after a huge loss is to regain, and never stop after lossing because the time for you to take back all your losses is to do it again and this time is more smarter and more strategic ways on how to gain.
From past couple of days my portfolio is completely in red due to all coins which I have is being bleeding badly. But as already faced such time before so this is not new and I do expect it can happen anytime whenever market falls . So I overlook such things and just take precaution if I can sell some and buy other coins which has fallen more and has a upscale in coming time.
