if you buy bitcoin in 220 ( yesterday ) and you hold and invest it now you get 10% chance
that very high profit than you lost your money at HYIP
So it all depends on luck and a bit of skills/knowledge. You might end up making profit or might lose some.
Investing is a risk. So invest if you can afford to lose. Again save half of the money as you might need them during emergency.
Yes anything is possible in the future. You completely cannot rely on bitcoins for the future and cannot afford to believe that it would help you out in making profits. The future is uncertain and unpredictable so it is better to invest into multiple products.
