I like Ethereum and Bitcoin Cash for the longest term value.. I think Bitcoin will continue to go up and then abruptly collapse once people realize there are 100's of much more liquid alternatives and the whole crypto economy moves from speculation to actual transactional use. I think Bitcoin Cash ultimately wins out over Bitcoin - since it's basically following the original white paper Bitcoin protocol to the 'T' without the Core group corruption (people that came in and took over management of Bitcoin away from the original programmers) and is easily the most liquid crypto. I'd have to write a book to explain everything I know about crypto.. all I can say is you can pretty much randomly invest in a smattering of the 'top 20' or so by market cap and you're likely to make money.

The biggest thing crypto has taught me about investing overall: NEVER SELL ALL OF A WINNER - NO MATTER HOW BIG THE GAINS ARE. You might sell after making 2000% gains.. and miss out on the other 48,000%. It takes balls to hold through anything.
