I think that at this time it is difficult to invest safely to make a profit. Be careful with HYIP projects, Ponzi, because it's so dangerous, it can cost you all the money you have. To earn Bitcoin and get the profit from us think you should join the business and trade some kind of altcoin, of course you will have to learn to have experience doing those things. If you know business it can help you make a lot of money. You can also join the signature campaign in the forum to earn more Bitcoin

There are more investment like casino sites. Most of the newbies in bitcoin are investing in HYIP because they think this is the fastest way to make money they are not aware that HYIP is s scam
Investing in casino bankrolls are a lot of safer than HYIPs because they are just a site for temporary or short term and not for long term like casino, most of the signs of hypes, they are offering big returns in a short period of time unlike in casinos that they are offering an average return per year and not short term because they are more like secured and stable business rather than HYIP.
to me i think it is not the right time to invest your money anywhere, because the price of bitcoin is expected to increase, therefore to me i think it will be more better option to simply hold bitcoin and not to invest it any where. as if the price of bitcoin goes high then it can also give you a good profit. therefore holding bitcoin is more better than investing it anywhere else.
Holding bitcoins will be slow for you to earn or make money while investing can boost that slow process into a new level where you can easily earn up to 10% per month from your investment while just by holding, there is no assurance that you will earn money because the market is so volatile and you can't be sure that everyday the price will go up.
