Would you still consider it worth getting an OTC rating?
Yes, absolutely. Being in the OTC is the cornerstone of being involved in BTC finance. Also, see
here.
Well, a WoT for me is a thing that allows to build up a pseudonym that still can be trusted. If some "Giszmo" made transactions to the benefit of 50 counterparts, it is very likely he will not run with some $200. If he acted to the benefit of 5000 people, most likely running with $10000 wouldn't be worth the pain loosing the great standing in this big community.
But
I'm Giszmo=Leo Wandersleb with a registered business, zillions of ways to contact me etc. If I want to get to the point where people give me $10000, going through the OTC and *trade* is pointless. I don't trade, I write software and OTC is a trading platform so I will mostly find traders there and changing 1.01Ƀ for 1Ƀ to gain ratings is kind of stupid and mostly done be scammers, don't you think so?
