BCD this time trading prices are very different in each website. I know that BCD has no official wallet and can not withdraw. But is that okay? Should I invest at this time?
I wouldn't trust this for a typical arbitrage oppurtunity.. this coin has been pumped and dumped quite a bit.. and even with arbitrage you can likely get burned or get stuck waiting for a pump for weeks or months.
Theres really two outcomes from this that will happen and both are negative..
1) You'll go for the arbitrage flip and realize that the exchange where its lower or higher has a wallet in maintenance or down...
or
2) even worse the arbitrage when you buy small works and teaches you poorly so you go bigger next time and really get burned.
My rule of thumb is if arbitrage is breaking more than 5-8% then theres gonna be bots firing off every second to hundreds if not thousands of people.. and if the arbitrage price isn't correcting with all these people involved, its probably for a good reason. Please be careful with this coin because other than occassionally really pumping, this coin has really no value or use case.
My vote is avoid this altogether, but if you do it.. go small.. and even if successful don't let it dictate future moves.
Good Luck.
