This could result in a significant increase in the prices of altcoins and their wider adoption. Bithoin's settlement could best be captured by Ethereum (ETH), but also by Litecoin (LTC) and Bitcoin Cash (BCH). Also worth mentioning is Ripple (XRP), which has a similar chance as ETH. XRP, however, enjoys high support and adoption in the banking world. The list of partners integrating Ripple is expanding. Ethereum, on the other hand, has a very wide user base, and because of Bitcoin's heels on the heel, it's probably no wonder.
