Bitcoin will end when there is no coin to dig. What opportunities are waiting in this space?
No coin to dig? then bitcoin will end? how come? bitcoin has been standing alone even before without those altcoins so how can you say that it will basically end? Bitcoin is depending with those coins? nope. It can will survive for real even without them.
You are missing the opportunity if you keep looking for those opportunities that you'll never find when the real opportunity is in front of you already.
