According to this news
https://www.reddit.com/r/jex/comments/a78wxw/what_does_it_mean/The 53rd largest BTC address,
15xZvLJLAgxh8cxEmAbpx1H35oibHo5cLA
Has been adding +249.999 BTC
pretty much daily since Nov 28, 2018
Current Balance: 14,950 BTC
($52,185,839 USD)
Holds 0.08578% of all BTC
This might suggest that there will be a surge for BTC and other cryptocurrencies?
Well it's the 53rd largest address, it's not huge news. It's largely irrelevant, in fact.
Not to mention it could be a whale who's simply consolidating all his coins into one wallet.
