Either some people are trying to trigger another BTC rally or it is related with the massive dump in Tether earlier. Either way, some people definitely took some profits from the pump as there was a sell-off in btc. Now let's see if we can consolidate around the current levels (6900), since we went past the last resistance level (high 6.7k), it'll be great if we can stay at these levels for some time.
Not sure why everone is fleeing USDT right now however.
Timing is weird, perhaps there's some insider information going around which scared some people off (?).
