You can try to find low market cap coins with really good features i can suggest one DeepOnion which has good features like DeepVault and DeepSend is coming very soon and maybe DeepTorrent so its a good one.
whatever coins we have of course must be with our beliefs and I still believe and have confidence ETH is a long-term investment that will bring profit in investing
I agree ethereum is the best currency from DeepOnion for long term retention the risk here is much lower and more profitable. Traders choose ethereum for long term investment in the case of other Altcoins their guarantee is much lower.
