On April 12, the number of deposits on the Bitcoin exchange reached its lowest point since August 2016. Recently, there has been a trend for Bitcoin holders to transfer their assets from exchanges, some of which have been particularly hard hit. For example, the number of bitcoins held by BitMex and Bitfinex has declined significantly in the past few weeks.

Another reason is that although the number of transfers to the exchange has been greatly reduced, the inflow of bitcoin into the exchange has remained at a high level, which indicates that the average size of bitcoin deposits has increased.

Therefore, most traders and investors may want to keep their assets away from exchanges for better custody.
