I think it's very risky if you trade all your money into bitcoin, the bitcoin price is now going up, but we have to see any future can happen including the drop of the bitcoin price. It's good for you to exchange half or some to avoid that risk.
Nearly, it is not a big risky but it is not a right that we use our all money on bitcoin or any other investment. But i rely on bitcoin and bitcoin always give us profit so i never see anything bad on bitcoin. I want advice you better to use your half capital in bitcoin and then testing it and if you get success with bitcoin then invest more.
I can't see why people are asking to turn their all money into bitcoin or other coins. They don't have to do this. There are more options such as moving with portions of the money while buying and getting bitcoin.
