Well I can say that in trading nothing is left to chance.
I think to leave to luck is to buy a lottery ticket and be lucky to win it, that is luck, I do not buy lottery tickets,
Now as far as what you're doing, that's not tranding, that's 'holding' a coin.
I am absolutely sure that you are aware of the basic principles of doing what you are talking about, and one of those principles is that you should invest what you are somehow willing to lose, if you have that clear, you have already won the way..,
