Every month I buy Bitcoin from %50 of my wage. I think it's the best saving method for long term. I don't do trade much, it's too risky for me.
Nope, trading is not risky as gambling or may be mining altcoin. I think trading is much fun to play it, because it has a lower risk than others and you can
get good profit too from that so start on taking this as one of your income besides signature campaign or even faucet
The risk isn't lower, you're just lowering the possible gains and loses.
Say you have $1000 and the same in Bitcoin and you gamble with one and trade with the other. Playing in a casino may get you broke in a couple minutes, but you can also double the money if you're lucky. If you're a bad trader you'll need days or even weeks to go broke, but it will also take days, weeks or even months to double the investment.
that's the point "if you are a bad trader" what if you're not? trading instead of gambling, require some skill in TA, if you are good in TA, you can somehow predict the next move of the market and come out victorious almost always on short term
predicting long term is more hard, and this is the reason why there are many shorters lately
