Asset popularity is defined in Shrimpy as the percentage of user portfolios which hold this asset. This means whether the user portfolio holds 1% of this asset or 100% of this asset, they are both treated the same. These portfolios would both be treated as holding the asset.
This value is calculated by determining the number of portfolios which hold this asset divided by the number of total portfolios on the Shrimpy platform. An example would be if 55 Shrimpy user portfolios hold BTC and there are 100 total Shrimpy user portfolios, the asset popularity would be 55 / 100 or 55%.
The purpose of this statistic is to give an idea of how common it is for this asset to be considered for inclusion into portfolios. The more portfolios which include the asset, the higher the asset popularity.
