This sounds too risky, if you want to send someone ethereum or Ethereum based tokens why not ask the person for his/her ethereum wallet address instead of going through this risky process and the person might not even know you sent anything if the person doesn't use the ethereum wallet.
You are right this is one of the best time to promote Bitcoin, the world is on lockdown and a lot of people spend time online which means that promoting Bitcoin now will get it seen by even more people.
The only thing hindering me is that i don't spend time on social medias (except WhatsApp) which i can use in promoting Bitcoin online.
I don't think that the amount of Bitcoin used for illegal activities can actually be know because illegal activities are private and people can't know if or when it happens or how much of Bitcoin was used for the transaction.
Bitcoin doesn't have an official logo but the current logo that people use for bitcoin is good and even the logo's people are submitting here is similar to it.
