Volatility is part of the game. It is absolutely normal. Volatility works both ways - up and down. One doesn't deserve the ups if he cannot endure the downs. Separate price from value. Get used to volatility.
Everyone is always looking for the next asset to outperform, be it stocks or crypto or hard assets like property. Textbooks always teach diversification and in a way it makes sense as you will not get wiped out totally in you are concentrated and your investment fails. Portfolio sizing is important. Take care of your downside and the upside will take care of itself.
