Definitely skill based gambling is more risky. You have to depend on the game fully which can be manipulated easily anytime. And ultimately you have to lose once or even more times. But in trading the case is whole different. Analyzing the market anyone can make money out of it.
Yes and any type of gambling is risky and you cannot expect positive results from it every time but if you are aware about price movements and current scenario of market trend then you can easily make some money by putting your money in trading.
But I believe sports betting is less riskier than trading. Sports betting must be one of the gambling type, no one could ignore this still it is better than trading for consistent profit making. Bitcoin trading could be an exceptional but compared to Forex trading or altcoin trading, sports betting is always profitable for me.
I love skill based a gambling because it has very less risk. Trading bitcoin is good because if we are holding bitcoin we can make profits, but sports betting is capable of giving instant profits unlike bitcoin trading.
Sports betting is a good way to make profits if you have good strategy and skills and if you can read the game well on the other hand trading is also good but it will be time consuming to make profits whereas gambling will give you instant results.
