There's no doubt about that. Yes Bitcoin is a new technology that people should take advantage on in anyway they could possibly understand better, either investing or trading. Although the investment aspect of bitcoin is better than trading but the fact that everyone doesn't want the same thing, some people will not invest in it, they will rather trade it and few others will not join cause it's volatile.
Whenever i see someone suggesting Bitcoin trading/gambling, my advice to them is always the same, and that is to avoid trading by all means. Yes there are people who are professionals in trading and are probably making good profits from it, but that doesn’t mean that it reduces or eradicates the potential risks associated with trading. Yes even Investing has its own potential risks, but it’s in no way associated with trading/gambling.
And the sooner we start to realize that Bitcoin as a long term investment is more than just an avenue to make quick profits, then the better for us. A lot of people who had the chance to buy and trade bitcoin in the early days of Bitcoin are probably still probably doing the same thing today. There’ll always be a huge difference between a long term HODLer and a short term trader, irrespective of the fact that it’s the same asset, the result would definitely be different.
