Hey dude!
This is your opportunity to earn more BTC and make more profit since you collected more kind or ways of earning money now.
I guess now you are earning enough for that.
Anyways, I guess the best here is investing your money but too much risky especially to those beginners without background of investment industry. In gambling, you can also have 100% winning and chances to have money back and also having 100% chance of losing your money in one snap. Trading is great too for money making and profitable but then scammers can also hook you to some offer they can give.
This is just few of my experience so better look and make more times of thinking the way your money will grow.
Just take note of this.
Spend your money and ready to lose so it will not break your heart bro.
Said, said and didn't give any hint about how to increase btc. Talking about trade, I agree with you, it's hard to make a decent and profitable trade without danger. But when you talk about gambling, I don't agree.
Gambling is not so hard and impossible as you are saying, it's very possible to make profit being responsible when betting. Follow the right method, preferencially create your own. On youtube we have many hints to follow and another's feedbacks. Gambling is my favorite method to increase btcs.
