I too have had episodes of worry recently...I totally believe in the future of Bitcoin in particular, but had to rationalize how selling a small amount could make a difference to my life at the moment. The media hype and relish when the prices start falling has to be seen for what it is, like when they cover anything else! Hold tight if you can afford to do that and you still trust in Bitcoin's potential. As said on here time and again; if you read the philosophy behind the technology then your outlook will be different to those recent folk jumping on board for a quick profit. If you are really worried then maybe it is better to settle and get out rather than being unable to cope with any losses. Crypto is not worth giving yourself a hear attack over, after all
