I think digital gold is BTC, silver - LTC, bronze DOGE, oil - ETH, gas - DASH

Mine was LTC BTC ETH and BCH after the dump of BTC long time ago i panicked and i sold all of that sh*t to real money. But I have no regrets or whatsoever i just want to use that money for the matter i have and it was probably important. Thinking back i sold a lot of alts and i profit from it afterwards.
