1. Slow confirmation time: Bitcoin transactions are slower than Stellar transactions, so the platform needs to wait for a given period of time before it can confirm an investment or withdrawal.

  2. High Fees: Bitcoin transaction fees vary widely, and sometimes it can be expensive to spend Bitcoin.

  3. Absence of assets: Since Bitcoin doesn't support assets, there is no ready solution to adopt which can replace assets on Stellar. An alternative is to get rid of assets and handle only proofs.
