I will admit that I am not a fan of the beer trading. I always seem to think that I am missing some unspoken rule when swapping bottles. Plus I am not a whale hunter so what I have in my cellar impresses only me in most respects.
But if sites like BottleTrade can become the “bridge” to safer trading then I would be remiss to not recommend at least checking their how-to videos out to see if it works for you.
So do that, if you want.
