I want to find out why everybody wants to invest in altcoins, what I want to ask is, how much money did you get from altcoins so far?
I can't remember on how much I've earned with altcoins but it's more than enough to be happy with my regular salary for few months.
During the peak times, I managed to took some profits from other altcoin investments that really gave me another source to invest all the profits to bitcoin.
This..
I think in the long run there will be only few coins surviving. Bitcoin will most probably stay first.
Other altcoins rely on the BTC, so in terms of investing in long terms, BTC would be best.
