There is a famous book by Benjamin Graham called "Intelligent Investor". It describes an investment philosophy based on underlying value of security. It brings up two basic points:
1. If you don't have a lot of time to spend on investment, just buy a mix of stock and bond indices and hold them forever.
2. If you do have a lot of time, look for undervalued assets. He also proposes some criteria for deciding if a stock is undervalued, e.g. a company's market cap is lower than the value of assets it owns, it's undervalued.
Does value thinking exist in cryptocurrency? Speculation aside, crypto should be driven by the same basic forces as fiat. People would want a crypto token if they want something that can be purchased with the token. Do crypto investors look for underlying value of a token? And if they do, do they look for undervalued assets? Is it even possible in the crypto world?
I think it's too hard to analyze which is undervalued coins at this very beginning stage, as you see most of coins have the same functions and road maps. For me, I just buy and hold some big coins which should have good dev. & marketing team.
