We have no idea on who is the owner of this address is, all we can do is speculate and guess so I think it is better to leave it be until we get more information that can point to the owner of that address.
If this is not from an exchange or from huge company, this simply means someone is accumulating. Hopefully this is not being accumulated to be dump on the current dipping market. If it does we might revisit sub $20k BTC price.
If its actually not an exchange or a big org or corporation that owns that wallet and the owner decides to dump BTC, at this time, we will probably go below $20K not because of the dump by a single entity but because of the cascading panic sales that would follow suit. Bitcoin movimg from $16K to above $30k in recent times restored some confidence in the market which will be lost if someone starts dumping bitcoins in quick succession similar to the dump that happened last week but messier.
I hope not. Its crazy the possible ways it could go if the owner decides to go rogue against the market.
