title_body: "min-ada" bottleneck to Cardano analogous to "gas fee congestion" for Ethereum?
upvoted_answer: No, it would not be a bottleneck if Cardano implements babel fees that will enable you to pay (actually arbitrage) your fees in different tokens.
  That being said, to keep a decentralized network secure, you always offer something of value for the work of validation blocks. Also, the author of the transaction might not be necessarily be the same party that pays for it.
  In the future, most of the transaction will be probably one layer above (for example Hydra) and the final fee will be paid only for a settlement.
