All this agument of trading vs gambling does not really matter to me, all that matters is buying bitcoin regular with the amount withing your capacity or buying bitcoin with amount you can afford to lose with a long term goal having a disposable income that can keep you going, and working out other ways of increasing your discretion to be able to increase your regular weekly investment as fast as possible to meet up your target of the amount of BTC you have planed to buy and HODl for a longer time, before bitcoin becomes more expensive than expected. I think that is what we should be talking about right now instead of bla bla bla trading and gambling.
I love your idea of using the dca method for Bitcoin investment thats one of the best step any investor could take, a real Bitcoin investor thinks long-term and accumulating more whether in bulk or bits is one of the best ways to secure wealth for the future through Bitcoin. Well that doesn't leave out trading or makes it seem useless cause there are several Bitcoin traders who are making profits from it and can still use their daily or weekly profits from trading to invest on a long-term, everyone mustn't be a trader infact it requires a high skill set and deep knowledge in analysing the market therefore everyone should stick to what works best for them without looking down on other methods of accumulating wealth through Bitcoin.
