well its your choice , you can reinvest in your services to get more profit, you can go for mining, you can buy some altcoins or evn you can go for gambling on your own risk and you can have fun, buy some things you really like or keep in your wallet for the increment of the price:)
Yeah, I think the most important thing is to not go for ponzi schemes. Do not waste any of your money on ponzi schemes, because they will scam you in the end no matter what. No chance you will get your money back from them.
If it sounds too good to be true, then it probably is.
But still many people are fooled by it because they want to earn fast and big. They don't know there are many ways to earn bitcoin. They like ponzis because it is easy to do, you just deposit and wait for your money to increase not knowing that all ponzis have the same motives. It is to scam people and steal their money.
