Bitcoin is a scam because it is shit as money. Btc incentives hoarding and price manipulation. When a coin comes out that ties the value to the market participation and incentives sharing and spending and new market participation bitcoin will die and take its place in history beside myspace and beanie babies.
On the contrary, I think it'll go down in history as being one of the first successful crypocurrencies to make it to mainstream adoption

But who's to tell where it'll end up, definitely not me or you.
