Personally, I'm not a fan of commission-free trading, crypto or otherwise. I believe it generally leads to artificial volume and price manipulation. There's nothing to prevent algorithmic High-Frequency-Trading to "target" a predetermined price and attempt to move the market in that direction my making hundreds or even thousands of trades in a short space of time. It's not the same thing as genuine price discovery in a natural market. I can't, in all good conscience, agree with this being "great news". This just looks like another time-bomb waiting to detonate. I'll be steering well clear.
Well this was what happened in the Asian markets and then the government jumped in to regulate these markets and the
price took a nose-dive. {Still remember that?} ...I have to agree with you, I do not know if this is such great news for us.
The other thing is, this is also not accessible in all states in the USA, so it might not have such a huge impact, with 1000s
of people only buying very small quantity of coins.
