According to LongHash, the reason why SegWit adoption rate on the Litecoin network is higher than that of the Bitcoin network, Longhash analysis seems to have two key factors: 1. Blockchain wallet does not currently integrate SegWit, this wallet still accounts for at least 20% Bitcoin network activity; 2. Veriblock (a project that uses bitcoin transactions to increase the security of the coin blockchain) has a huge impact on SegWit adoption rates. If Veriblock doesn't exist, and companies like Bitpay and Blockchain can upgrade to SegWit, Bitcoin's SegWit adoption rate could reach nearly 70%. As a result, the adoption rate of Bitcoin's SEGWIT will be much higher than 50% of Litecoin. In addition, if the fee rises to a high enough level, then Blockchain is likely to use SegWit, while Veriblock will use Bitcoin blockchain less. Until then, Litecoin may continue to maintain its advantage in SegWit adoption rates.
