There are a lot of sharks out there and bitcoin is risky enough as is buying and holding . Do not invest your bitcoin outside of buying and holding for the dis-inflationary bubbles. Do not gamble. If you are a thrill seeker pick up extreme sports or tell your girlfriend that she looks fat in those jeans.
I earned Bitcoin with my effort. Therefore, I am very precious it. I am rarely gamble. I know there are too much scam site so I hope you can show me if you know a trust site and I sincere thanks for your advice !
Bitcoin is a horrible currency to lend and will have much higher default rates than inflationary fiat currencies. Day trading is another form of gambling.
Buy and hold your bitcoin is your safest bet with probabilities of greatest returns.
I understand that is boring but focus your efforts on making money other ways.
I sincere thanks for your enthusiastic help ! I know that it will be difficult for you to be able to confirm that a website is trustworthy or need to invest . As I understand you are not the owner of this website so you can not be sure it was definitely legit site or not ?
I also know that most of HYIP, Ponzi,... are scam site. The only problem is the time.
However, I mean if you can recommend the site you have been investing or you know that it was still good pay.
Once again, thanks so much !
