it seems that it can happen considering that bitcoin / crypto uses P2P technology without central authority, the transaction process is carried out by networks that are not supervised by the institution so that it may make it easier for politicians to invest without the knowledge of others.
I'm sure many politicians are playing bitcoin, but it's closed because maybe bitcoin in their country is considered illegal. They realize that bitcoin is a good investment for the future, so they are interested and enter the bitcoin market. Bitcoin applies a peer to peer system so transactions cannot be tracked, and politicians are safe to conduct bitcoin transactions. Because bitcoin is anonymous.
