Also, I am looking for long term investments like I wish I had invested 100$ in bitcoin in 2010, anyone believes such opportunities still exist?
Opportunity is created every day and exists at all times, but you are looking for the easiest way to make profits at all times. While the opportunities are created daily in this highly volatile market, it is easy to make profits easily.
bitcoin may rise to 100000 dollars and your 100 costs must.
it is better to use that money to learn more about investment, this learn will make you make your growth eaily
