I am just gambling actually to make bitcoins. but the problem is I am loosing more than I win. I hope some nice sites come in market where I can invest and rest assured that I will get profit always
First of all gambling is an assured method to lose money. In casino games the odds are always against you and so you cannot make money in the long term since the house edge will make you lose. Still you can earn a bit if your stop while on a green streak. But best method is to stay away from gambling.
Investments are good as long as they run profitably. Trading is the best of them where you are actually investing money into bitcoin or other crypto. Mining is good for some people. But the best method is to work for money and invest it in some real life business which you know wont turn scam.
