This said we need to note that cryptocurrencies are not a normal investment. The volatility grossly exceeds that of any other investment class. It is to some parts unregulated. There is the risk that cryptocurrencies get outlawed, that exchanges get hacked or that you lose your cryptocurrency key. Cryptocurrencies are a high-risk investment.
So an important advice is to only invest as much that you can keep on living and be if all of it goes to zero.
Yes, cryptocurrency is not a normal investment alike in real life investment. Most of the time, we are always risking our money, time and effort but in the end we lose. Cryptocurrency is a matter of time, a lot of coins bullish over a period of time and it is not necessarily that you invest now, you are a millionaire of tomorrow. There are times that you need to withdraw you capital even you did not reach your expected price, there are times that the exchanges are being hacked and the worst is that, one of your account will also gone and there are times that the price in your portfolio always remain the same even you put your capital 2 years ago. That's the life of a trader, there always sacrifice and risk whenever happens in our capital. But in order to avoid these, we must have a knowledge to control unexpected events. Trading is like a gambling, we cannot earn money if we will not gamble it.
