If planning to HODL, just stick to:
1. BTC
2. ETH
3. LTC
Currently stuck with just ETH, made a mistake in my portfolio.
Planning on taking on more LTC.
These are the core ones for holding, we need something which can make big profits rather than the core, stable ones. For example erc20 tokens and project coins that can be bigger in the future. They're better. Aventus, AVT tokens for example. Or PPT tokens.
