The risk of investing to bitcoins is higher than before since the price difference from the first it started is quite huge and it can increase much more. Unless you can predict and know how to play the price or how stable the price is, the lower the risk it can affect you. Mind you there is always risk in almost everything and you can't just eliminate them. Nothing is absolute.
I agree that now the risk to invest in bitcoin is much higher. Nobody can predict the price and in case of a fall you can lose everything.
You will not loose everything even if price goes down as price will never fall back to zero and if it falls to zero then only your will be loosing everything but I don't think that will ever happen and I don't see any risk in investing in bitcoins as the price is continuously increasing.
Yeah that's absolutely right that's there's nothing to lose if price will go down but not possible to zero because as of now price is very healthy and kicking. The very significant situation here is making clear to it that the most risk in bitcoin investment is that more btc investments adds were now circulating around the world, promises higher profit gains that is more prone to ponzi scheme and your investments might be scammed secretly by their tactics. On that worst situations investing any advertised online investment offers, you should not entertain them and don't give them a chance to rob you using underground tactics.
