The percentage of Bitcoin's dominance in the market is getting smaller and smaller. Already now it is 32%. The closest competitor is Ripple, whose market capitalization is already more than half of Bitcoin's market capitalization and 20% market share. Third is Ethereum with a capitalization, which almost reached 100 billion and a share of 12%. The capitalization of Ripple and Ethereum is the Bitcoin level of the November period, i.e. his level, which was just a little over a month ago.
Ripple, Ethereum, Cardano, NEM, Stellar and some other large assets - are the cause of the lack of growth in Bitcoin. Big players understand that other liquid assets with the potential for growth appear, and they are not terrible to invest, because at any time you can withdraw your funds without affecting the cost of the crypto currency in the market (without crashing it).
Can Bitcoin stop growing? Of course it can. The only thing that saves and pulls it up is popularity. Most people who are not in the subject and have heard about crypto currency, know exactly Bitcoin and with a high probability of investing in it. Perhaps Bitcoin will become a storage medium, and may even lose its value and lose competition to its improved competitors. Because of the large problems in Bitcoin (huge commissions, scalability, etc.), it's hard to see his bright future.
