No. It isn't. An investment produces wealth. A trade redistributes wealth. There is nothing wrong with trading. It just isn't investing.
Def of invest: "put (money) into financial schemes, shares, property, or a commercial venture with the expectation of achieving a profit." Sounds like trading to me. wouldnt you agree?
Yes, just diversify your portfolio. And set your goals, are you in for the long term? If you're worrying about the volatility, you may want to consider investing in stocks that are focused in blockchain technologies just like COIN and $BTCS
Crypto is only 5% of my portfolio, but the bull times are back now. Going up very fast - doubling every week. Let's see, for how long... Shiba goes up like a rocket; doubling almost every 3 days... Long position on all currencies - so even if Bitcoin goes to 100,000 I'm not selling.
