I have tried a google search but with no luck as to what the costs are for storing content on the Tezos blockchain, if these costs are kept on a level if the price of XTZ goes up, plus what are the simple (I'm not a coder so simple is the word here) mb of data that I can store and how much can this be changed - ie store a text file of what size.
Many thanks,
Dominic
Storage cost per byte is defined in protocol constants (see "Byte cost"). For the current protocol it's 0.00025 tez per byte that means you will pay ~262 tez for storing 1MB of data. Note: this value can be changed in following protocols.
You can store any amount of data in lazy storage (aka big_map), however there are "Hard operation storage limit" = 60,000 bytes (this value can also be changed), that means if you want to write a large amount of data, you will have to split it into ~60KB chunks.
