I love to trade, and I would have to agree with @ll_jay890. It's not a serious choice because serious trading needs a few things that the DEX and GUI lack.
It needs order management, it needs to be quantifiable in terms of risk,
it needs a great API,
and it needs the capability to place leveraged trades.
The reality is that the fact that D in DEX doesn't sell itself, it needs to just be the best exchange, providing a superior way to trade. The reality is that traders right now want to trade on Poloniex for exactly those reasons, regardless of how Poloniex has been implemented.
The thing that's frustrating to watch is that what DEX offers is extremely desirable to traders, safety. If trade could be leveraged from one's own security, it would lead to a much deeper reflection of the tokens traded and a consistent, healthy threat of major price action.
The problem with taking your money off the exchange and trading on the Dex, is the possibility of losing money due to the complicated nature of placing trades. This is especially relevant for shorting.
//Right now the odds of losing all your money on a centralized exchange due to hacking is far lower than losing a big chunk on the Dex due to //complexity, user errors, and bugs. Also there is no chance of fund recovery on the Dex if a bug causes you to lose money.
The longer that polo and all the other CExs stay secured, the better their practices will get and the less useful our Dex becomes.
I've day traded for 10 years and I would never trade on our Dex in its current form. It doesn't have the most basic tools that traders need.
Please consider withdrawing your bts from external exchanges if you do not intend to sell them.. More than 30% of BTS are in the top two exchanges. This is very dangerous and if something goes wrong with any of these exchanges you can kiss goodbye your bts investment forever.
If you do not sell your bts, why not just held them in your wallet and be the king to your castle?
