Your point is 100% irrelevant considering BTC has been successfully registered several times and none of the businesses that have registered it could even remotely be considered in the same industry as a technology or bitcoin business. And unlike you, I'm not a scammer and I'm willing to accept escrow on the domains I sell.
1. Does the business claiming infringement operate in the same industry as your business?
Remember that trademark's guiding principle is "do not confuse the consumer." Thus, if it is really unlikely that the other business's customers are going to be confused because you have the same name, then there really isn't a trademark issue. One of the factors courts look at to determine likelihood of customer confusion is whether the two businesses are in the same industry.
If your business name is identical to another SEO business, then you could be screwed; It certainly requires caution! However, if you provide SEO/M services and the business claiming infringement designs cookware or provides financial services, then there is really not a trademark issue. You're not screwed.
