There are daily new alt coins coming out, many people just copy-paste and change some params to make new coins, and these new coins trade in different exchanges such as cryptsy. Is this making any sense? My friends told me by making coins like this, each coin they can make 2-10 BTCs, much faster than they mine BTC directly. I guess soon the alt coins will be saturated as it is so easy to make one. Any comments or opinions there?
