There are a number of ways to make money online with or without a website.
I doubled my bitcoin(10BTC into 20BTC) in the last 90 days by investing to some online investment programs and some p2p loans.
No risks, no gain; More risks, more gains. Forgive me, I won't expose and recommend the project which I doubled my bitcoin, as I know that it is very risky to invest in this kind of investment projects and need to do lots of research before investing my money. This way maybe fit for me to make bitcoin, but not for everyone.
What way do you do it?
I tried to increase the number of my bitcoins investing initially in mining myself. At the beginning with my gpu. Earned very few. Then tried to invest in cloud mining sites. At the first have doubled (end even e few more) the bitcoin invested. At the second earned my invested money. At the third lost almost all the investment. the results of overall actions in clod mining was a little earning (because even the investments was few: needed to prove the credibility of site at the beginning so the amount invested were few). There are about two-three months that participate in signature campaign and the earnings are not indifferent (for the amounts which I talk). Then at the beginning participate in some kind of games organised from a site online (not more now) and had almost 1 bitcoin from those. Other 1.5 from the above actions make 2.5 bitcoin which are overall amount I had from my online activity. Not to much compared to those bought beginning two years ago (the first 4 bitcoin when the price was about 60 us dollar one bitcoin).
But I make a big investment with high risk. Hoping to have more. Now those are blocked in an investment which, as I see, have big probabilities to be lost. The hope die last but the hopes to have again those (are not few but invested when the value of bitcoin was low so seemed a little amount when was invested) are very, very few. If I would have those in my wallet I would consider myself as a well holder bitcoin person. This kind of investment make me feel bad when remember it. I invested to many bitcoin there and I must not to do this. But was new in the world of bitcoin and full of hopes about investments in this invention. Having faith in the people which taken those. Hope that they will be such. Even the fault of the actual situation is not largely theirs.
