I do the same thing at the store. To a certain extent, I buy what's on sale. There are certain things that we have to get a specific item because the regular one contains something that we can't eat, but for the most part, I try to stay brand and flavor-flexible. If Fuji apples are on sale this week, that's what I'll eat. If Gala are on sale the next week, I'll switch to that. It's an easy way to save money.

I think one of my issues with looking at crypto like this is that the value of the strawberries you bought was well-defined. We all know that a pint should cost around $2.00 if it's not on sale. The problem for some people with using the similar style for cryptos is that the crypto is an ownership in a company, organization, or group. It's value is flexible. For an uninformed investor, the drop in price could be related to tangibles (CEO leaving, anti-trust investigation, lawsuit, etc...) or it could be FUD. If you haven't done the research, it's hard to keep up.

Also, because all of this is so new, it's difficult to tell what the "regular price" is for most cryptos. I know a number of people who got caught day trading crypto because they bought at sale prices in January, only to see the bottom fall out. I think as the markets get more mature, the prices will level a bit (sort of like the stock market) once people really figure out the value and some idea of a P/E (price to earnings) of a crypto.

All that being said, I agree with you. I can't give investment advice, but if a person really believes in a specific crypto and thinks it's going to do better in the long-term because there aren't any real reasons for the price to be depressed, it's a great time to buy in. Why not save the $1.25 on strawberries. You're going to eat them anyways. :)
