After I known bitcoin, I think is the best that promise huge profits, so I took the decision to make the bitcoin as one long term investment.
as what? what field you chose to make bitcoin the long term bitcoin. bitcoin it self a long term investment. but you still need to choose something to do with bitcoin.
only holding bitcoin is good but keeping them circulating in profitable businesses is much better than keeping them in wallet and idle.
I think for now, the most profitable investment where you are guaranteed with lesser risk is by putting your bitcoins in a bankroll of a gambling sites at your choice, we know gambling industry is very profitable, so this should be a win-win for us in the long run. Just like doubling your potential to earn more.
this is what i was thinking, but i need to find a site where to make an investment and do not scam me
Even if you're going to invest your bitcoin to the gambling site, it still has some risk, there's no guarantee that the gambling site you were invested will not turn out to scam you and their customers.
The best option, in my opinion, is trading, or you can just buy bitcoin while its price is still low and hold it until you feel pleased with the price.
