Greetings dear @crypto.piotr, no doubt the DeFi projects have become popular and every day new of these projects arise. Unfortunately many of these projects are focused on short term profits and do not provide real support to investors to motivate them to invest long term in them.

Personally, offering an extravagant API is synonymous of alert since a project that has just started, has no support to maintain the returns of the same, as you express this type of API is only a way to attract investors and only those who enter early manage to capitalize in a good way, without forgetting the exorbitant profits received by those who obtained tokens in the pre purchases or stages prior to the launch of the project.

Regarding stability and scalability, I agree with you is to prefer to launch the project at micro-scale and then grow as the price of the token stabilizes, I say this thinking as a long-term investor.

Entertaining read my friend, regards.
