I think thats good idea but its not good when the crypto's have fallen down so much. I mean if you convert at this point then there is no valid point in doing so if we have bought the crypto's at higher rates than the current one. Its obvious thing that we will incur the loss though we convert it to the USDT or USD itself or whatever local currency we dive in. This is simple math and we should not be very sticky to it. Better wait for some more time and then we can see how the market perform in few days or weeks. This is the only right move at this point. Do not do unwanted conversions when its not needed. Better think about the brighter side when you hold and bitcoin go beyond the last ATH. :-) Selling at lower point and again try to see it go even lower could be very risk. Better hold and win the situation.
