With cryptocurrencies we control our own deal , we can easily make it to the top , yes it does have negative times and is risky but let's be honest , who doesn't ? Even dollar was going down !
But it also gives rewards like no other.
cryptocurrency is so revolutionary because it allows to exchange value directly between parties. It doesnt require that these parties trust each another, or that they trust an intermediary. It replaces trust in central organizations with trust in source code.
