Bitcoin is in, it is celebrated, it is rehabilitated... The Times, the President and so on. Everybody says that it is not scam, everybody assures that it is a good thing.
All this means that the risk level on Bitcoin as well as altcoins is lower than ever before. And the prices of altcoins are moderate, in fact they have not increased remarkably relative to previous year.... Does it mean that it is right time to buy or that this right time is near ? (I do not suggest to buy BTC with 100 000 USD !)

The only important thing is the risk/reward ratio.
