Keep bitcoin in your pocket

. This will definitely increase their value, but not the quantity. Bitcoin themselves are already an investment. By investing money in them. You want to benefit from the same thing over and over again. Don't be greedy

. Because in the pursuit of profit, you risk losing what you have if you come across scammers.
This is much better option for newbies seeking some good investment option to them and the only thing they will do for that is to let it sleep on their wallet then wait for the price to pump up.
There are so many scammers out there that's why its not a good option to invest on hyip or the one who promise us a huge profit in short time period.
