TA helps to limit risks ESPECIALLY when trading PUMPS like Ether. I know where to exit if trades goes against me.
I believe in Microsoft Azure. SOLID fundamentals and an actual product from a real company called Microsoft. Ethereum is totally useless and 2017's biggest ponzi scheme.
I will trust Microsoft and Oracle anyday over a a group of scammers that develop Ethereum. (which IS an unlicensed security)
If you are long, make sure you have a stop-loss.
