Thanks Magneto, I have tried it a little yes and accumulating bitcoin rather than fiat. I'm in a position where i can give it a practice run and see, so I might do a sort of research blog on it for the results. Should be fun, I'll let you know how it goes.
No problems.
Also one more thing, you could look at this site for some altcoin arb opportunities:
https://cryptocoincharts.info/arbitrage. I look at it when I have some spare time and analyze some of the opportunity it lists. It definitely won't be completely accurate and you'll find many of these arbs be nonexistent, but it's worth a look. Also as i said, take a look at individual coins coinmarketcap and click on markets to see the price differences.
Good luck with your venture, and I'll definitely be interested in seeing if this is really a legit way of earning an income.
Let me know when your blog has started.
