The detention of the founder of Telegram could negatively impact the TON coin, which is based on the Telegram platform and its blockchain technology. This could lead to fluctuations in the value of the coin and a decline in confidence in the project. However, the future depends on how the team behind the coin responds to these challenges, and on the decision of the authorities regarding the case. If the coin continues to be developed independently and with determination, the coin may recover from any negative impact, but the risks remain.
