Why are altcoin exchanged for btc and not for dollar?
having tons of altcoin is just like having bitcoin. If bitcoin grows, they grow. If bitcoin falls, they fall.
Isn't this pointless? Why not buying and selling alts for dollar?
I think it's all because Bitcoin is the currency of all cryptocurrency world and therefore all trades are on bitcoin
but in this way if bitcoin explodes, all will dies... there is no point on keep them... eth is also exchanged in dollar, why not the others?
