There's nothing like timing in gamble, and yes, timing the Market is mostly use by traders since trading has to do with short term profit which is why is not advisable for a bitcoin investor to be engaging themselves into timing the Market. However, the difference between trading and  gambling is very clear although the both almost work the same but the only difference between this both is strategy, though this same strategy is also apply in gamble, the reason why gambling strategy is different from that of trading is that no matter the strategy you use in gambling you can not be able to win in a roll rather the strategy can only reduce our chance of losing, but I have seen a lot of people making steady profit from trading through strategy.
