Well I suppose the worst that could happen is that locals ID you and try rob you. How many PM coin bloggers are out there? If there are few out there then why not? If you can figure a way to do it safely so no local thief figures the guy down the road has treasure to pillage, then worst thing that can happen is you get no followers and you waste your time. Or you are a strange man and people follow you because you are a circus side show, instead of for your coins and expertise. Best things to happen are followers, new friends, new communities, new knowledge etc. I say do it
