Hey @dangershony, I just noticed your note in the task:

"We should limit this on the invest page.
The cap should be 0.1 bitcoin?"

Currently, we’ve set a minimum of 2 BTC on testnet 😅

It seems like we have a couple of options (or let me know if you think of a smarter approach):

1. Add fields during project creation for setting both minimum and maximum investments. This way, we could set a cap at 0.1 BTC. However, this might not be ideal if founders later need to adjust these values.

2. Separate logic for TBTC and BTC on the invest page, though this could lead to hardcoding.

Option 1 (with some variation) seems like the better one, allowing founders to define their own minimum and maximum.

(in the meanwhile i'll just set the minimum for 0.01 and max for 0.1 :) )
