Cryptocurrencies have suffered mid-week losses across the board, with Bitcoin, Ethereum, and Ripple leading the way. Polkadot is back on the drawing board as a result of this week's losses. DOT made a dash for $20 the previous week, but the uptrend was cut short under $18. Polkadot is currently trading at $13.6 as the battle between the bulls and bears heats up. To get the token to $16, it needs to break above $14.5.
