Of course, I still believe in Bitcoin. It's still the King in crypto world. But, I'm a bit afraid of its development progress. Also, many people are coming in treating bitcoin as a quick buck scheme. Bitcoin has already strayed from its original purpose (in terms of decentralization, scalability, etc.), but don't mistake bitcoin for the entire crypto-currency and the blockchain technology. Many crypto-currency have a serious developer and research team and in terms of technology, bitcoin would not fit into the top 10 at the moment.
