Many industries and financial instituions have integrated with bitcoin so it will be the best choice since it is so popular. Though, I don't think about the traceable part because most coins are decentralized and not all have KYC. The issues that one might encounter are political. Certain coutnries have their own rules to "regulate" the use of crypto in the local market. Study your country's laws as well to the country of the receiver of the cryptocurrency before doing anything.
