I am earning and collecting bitcoin to bet on sports in future.Will it be a good choice to invest in it betting or other things.Where should i invest my bitcoin to have a long term profit?
If you only have a small amount of bitcoin then no, betting is not a good idea. Gamble with fiat if you only have a small stash of bitcoin's. Bitcoin is too precious to waste gambling if you don't have a lot. Hold onto your bitcoin, it will be worth more & more as time goes on.
A newbie should enter bitcoin if he will just gamble for fun but if your purpose to for "long term" profit, you are in the wrong place. You need to know more about taking risk and gambling doesn't fit you. Go for trading of alt coins that's even more worth of your time and you can take time to study on how you'll get long term profit there.
