Yes, i agree. But to speculation all of they are perfect...
Consider BTC also in cryptocurrency. I dont think BTC has a good future. I read Some where that BTC can be used for feeding Terrorist and other Illegal ways like black money transfer, Hiding black money etc. People can send their Black money any where with out being located. So i think it will have no future
All fiat money you can also use to laundering money or to feeding terrorism, but this topic is about spend or not to spend bitcoin...
Yes i know its my topic and i know for what type of this topic is, Any way my post was in answer of this question: I don't think that altcoins has good future.
