If you quit crypto world, that could be your life's biggest mistake. Leading a life without knowing one opportunity is different than ignoring one reliable opportunity, later may end up in regretting. I suggest not to take decisions of stop playing with crypto, but play carefully.

I do see some people suspect on your losses. I do not want to enter there. But I want you not to repeat the same mistakes. Holding for long is the simple requirement to stay within profits which maybe completely different for the case of altcoins.
