If you are new to the crypto world, you would be wondering about the typical jargon. HODLing is a concept that started with some typo by a BTC investor (he may have meant hold) and it got viral and it is now spelled HODL (hold on for dear life). Here are some quick tips on what altcoins you should HODL now that BTC is touching 20k soon.
EOS - (Ethereum 2.0) - Being developed by great team. Already proven with STEEM and more and more traction every week.
STEEM - (Facebook of new world) - Why should big corporates earn from your contributions and curation? Here comes STEEMIT to give the social media back to you.
DASH - (Bitcoin 2.0?) - Dash has been working to resolve bitcoin issues like transaction fees, fast processing and anonymity right from inception. It has developed great user experience now and moving in right direction to be a viable crypto currency for day to day transactions.
Litecoin - (Another option for Bitcoin 2.0) - Same advantages of speed and low cost. Also they have been integrating fast with exchanges and services. They need to work on user experience though to become viable for day to day exchange. They can not be a bitcoin me too.
