Polkadot reaches a new all-time high after breaking through the $40 resistance level. The upswing hit a stumbling block at $47, cutting the trip to $50 in half. Following a rejection from $47, Polkadot fell to $40. The digital asset has already resumed its upward trajectory and is now trading above $45. If the immediate support level of $44 fails to hold, upward pressure toward $40 will build.
