Crypto investments are new and super-risky. Remember ethereum founder saying that cryptos are so risky the prizes might actually drop to zero. Well, that doesn’t seem practical but the message was clear. Do not invest your life savings in bitcoin or cryptocurrencies generally. Just like John Draper noted, you still need to buy stuff in fiat. So while bitcoin will likely worth a lot more in the future, it’s advisable to invest just as much as one can afford to lose.
