Stop looking for things what you don't do it but improve those things what you allready doing it Im sure many of you are involved in crypto so get better with crypto.
What Ever you do it now just get better on this you don't need to search for things what to start just improve things what you have now.
Cryptocurrency is good, but its not something you can solely rely on. Remember, it's highly volatile. You may be making a profit today, but you may not the next day, or you'll get burned after a few days, so its better to diversify and learn other business stuff to sustain you and grow your finances.
I don't agree with focusing on one thing; 3 to 4 businesses as long as you can keep up is good, so if one underperformed, you have 2 or 3 to rely on and make up for your other losses.
