An interesting theory is possible arbitrage going on between bitthumb exch and binance. POWR was priced over 500% on bitthumb, however deposits and withdrawals have been closed for the last 6 months but was reactivated today. Traders are buying on Binance and selling on bitthumb to take advantage of the price difference.
There are 4 other coins that will have their dep/with reactivated today...lets see if the same pump occurs.
