Well, Bitcoin Hodlers increasing could be ambiguous in the sense that many addresses could be created not by noobs but by those already in. So unless we have a digested data on that we can't be sure about how good it is.

Adoption increasing on the other hand is something interesting. Adoption is adoption (literally😀), but the article you cited also didn't provide many significant reasons why adoption is spiking (well, to me...). The only thing I saw is that it's also referring back to the fact that new addresses are being created, holding more BTC and search interest spiked which may not be adoption (as i deem it to be👍)

But well, lastly, Bitcoin will have a sweet halving aftermath. My reason being that, many others are playing the "watch-and-wait" game and they'll hop and troop in when things start to go well.
