I think this is true for any investment. You should only invest in an asset after you have done thorough research instead of following someone else blindly. After all, it is your money that you're investing so if you suffer a loss, it will be your loss and not the person whose advice you followed. That said, I have invested in a crypto fund that has done well to diversify my portfolio so that I have high performing altcoins alongside bitcoin and can enjoy maximum profits.
