22M btc transacted today

[pooya87]

it is normal in the sense that the behavior looks exactly like any big service such as exchanges have. the blocks themselves don't have that many high value transactions, it is just that they are happening more in 1-2 days that they aggregate to a big total showing that spike.
otherwise these big transactions individually and the blocks containing them individually are normal.
for example there are lots of transactions like this:

which have lots of inputs from multiple other addresses similar to the receiving that are consolidating a lot of received coins.
when you move back you eventually find chains like this:

and the final one is being aggregated with other similar ones and goes in:
