Btcd is a scam or not. It doesn't matter.
The most important point is its have value and we are supposed to own it.
Anyone knows how to claim it with electrum wallet?or anyone already claim it?
That's the point... you can't "claim" it... it doesn't current exist. THERE IS NOTHING TO CLAIM. There is no code, there is no wallet... there is no blockchain!!?!
The only thing being traded on a couple of shitty exchanges are some "tokens" representing BCD "futures"... you cannot deposit nor withdraw BCD... IF you happened to have some BTC on these exchanges, they would have credited you these tokens... people are gambling that BCD is actually going to happen, or that it is a scam.
Those selling, probably think it's a scam that isn't going to happen and are happy to sell what they consider to be "worthless" tokens to suckers buying them for BTC... The buyers think that BCD is actually going to be a "real" coin someday... and are hoping that the actual price once it exists will be higher than what they're currently buying it for.
- If it turns into a real coin and price is higher than now, the sellers maybe lose out on making more money... buyers can sell at the higher price and profit
- If it turns into a real coin and price is lower than now, the sellers "win"... the buyers lose, but there is the possibility it could recover at a later date.
- If it turns out to be a scam, the sellers "win"... the buyers lose with no hope of recovery
For now, unless you had BTC on the exchanges handing out BCD tokens... you get nothing... If it actually turns into a real coin, then you can think about claiming them.
