there is no such thing as "wallets on bitcoin network", you can't just make up words and associate a random number to them. there is no way of counting how many "wallets" or individuals using wallets there are either.

as for the relationship between Coronavirus, Chinese stock market and bitcoin i have to say there still is no convincing relationship. bitcoin is moving as it was expected to move. this trend was predicted months ago, that is expecting bigger bull market in early 2020 that grows the closer we get to halving.

additionally the spike in number of transactions is a normal thing that happens every now and then in bitcoin specially when its price is either rising or getting ready to rise.
