let me clarify something for you if you didn’t understand about bitcoin trading and why you view it as something that is very hard. It's just because you find it hard to conduct adequate and deep research, and to find this research is definitely hard. I can’t lie, as a trader, that it depends on prediction and probability. Did you still know that those profits that you will courteously get from each trading for that interval of 4–10 years will be more than the profit that a bitcoin investor will gain in 4 or 10 years? If you think I am lying, go and make a rough estimation, and you will see my point.
I know you subjected to your own points of view and reasoning but no need using some terms which can lure more people into trading which you should have realized the effects at the early stages. Trading is profitable (undeniably) but considering that traders can never be perfect enough to always go in at all times and not take any loses from their trade. Trading comes with loss and profits which the trader is entitled to but what is said to distinguish between a professional and just anyone trading is the ability of making more profits than losses, now comparing to Bitcoin investment, anyone can buy and hold without any confirmation of professionalism involved. Bitcoin investment gives without taking, the amount of Bitcoin held doesn't changes and perfectly increases in dollar value as long the investor continous to hold. The profits are made considering the variability of the Buy and Sell order, so anyone investing understands the power of long term holding which guarantees good return of investment, more likely to be greater than those who traded for same period.
