The protestors need to use global exchange wallet. This can be a great rid for other protests area. They can safe their fund from locking. Obviously all of them needs to use global exchange for exchanging Crypto and BTC.

I prefer Coinbase wallet. You can use this easily.You will see two option to send fund wallet address and users mail. And transfer of fund to any coinbase users mail is out of charge.
