ethereum, bitcoin, litecoin, BTG. very nice coins for use in long-term investments and have a brighter future than the other. for one to four years is perfect invest in coins.
I agree with the fact that BTC, LTC and ETH are excellent long-term coins. But I can't understand what attracts you to BTG? I don't see any great opportunities here. It's better to buy NEO and NEM instead of BTG.
Obviously that coins are running for long time ago so there's no reasons to doubt with that, but for me these are the new list of coins that good to select for long term investment.
>VEN
>RDN
>SNM
>IOTA

>RLC
That's the best coins to that good to invest for many years, for now their price are seems fall down but I believe that in the future it will growing up.
