Yeah. I've never invested in alts. I haven't even put a cent into ETH. I think ETH is garbage and bound to implode given it's malleable nature.
BTC is where it's at. Ill stay with Bitcoin Core unless it doesn't scale in the future as it was originally intended to be; then ill consider a sidefork if i need to. But I am BTC all the way. Less fuss, more stability than other crypto.
*edit* I say stability because its your fault for trusting someone else with your coins. (exchange fiascos) Notice all problems with bitcoin circle around FIAT... not bitcoin.
