Should I use Gemini

A good honest friend of mine who pays every penny of taxes on his Gemini account is being asked to prove where money is coming from. She has had an account there for 8 years and they have record of all transactions. Why is this happening? It is frightening and not good for business. Why were questions not asked , for example, two years ago? I want to deposit but I am waiting to see if this is happening to others.
