Just because a wallet that was dormant began to have some activity isn't enough reason to believe that something's about to happen, let alone a bull run.

We're still in a bearish season, and we're lacking something that can function as the trigger that starts a new bull run. Last year it was hype, cryptos suddenly became popular and the general public began to pump the market with dumb money. We won't see the same behaviour this year as people already know what cryptocurrencies are and they know what could happen if they start investing recklessly in cryptos (a major crash).

There could be some upward movement in the next couple of months as bulls will probably trigger another bitcoin rally, but I don't believe it'll be as big as last year, so I doubt we'll see a new ATH. Then again, anything can happen in this market so don't take my word for granted.
