The nature of most crypto projects is decentralized, they are coded and manteined mostly by communities...other mantained by teams where funded by ICO or premines.. what means the team already have the funds to move on with the project. Is not something you shut down cause the price drops, most starts-ups including Tesla, Uber, etc are totally profit-less today and stock dependent... Monero, Bitcoin, Ethereum, etc.. they don´t depend on any profitability...
