3. hardcore btc ppl: will tell you that every alt coin is just bullshit, and only btc is worth investing
Yes, and the reason for this - crypto-currency *is* the future.
With only 21M bitcoins, if bitcoin is the only crypto-currency, those who have it now will be filthy rich due to the limited supply.
Altcoins get in the way of that greedy dream.
So greedy bitcoin speculators will want you to believe no alt-coin will ever make it.
Truth is most won't, but some have to.
