Very good advice.
In fact, I think that everybody should understand that crypto market is the same as any other market, stock market, Forex etc.
It's very risky so please be careful before investing.
The best strategy, in my opinion, is to invest only money youcan afford to loose and to diversify your investment.
Investing in bitcoin is not easy you need lot's of knowledge and patient. All kinds of business have risk and challenges especially in investing in bitcoin, you need to use your mind before you start to invest in bitcoin. Invest only money you can afford to lose.
