Its always funny to me to hear people wonder about whether bitcoin will continue to grow, and even whether its a scam, a ponzi scheme, etc. Almost always, these people have no idea what money is, what a blockchain is, and what bitcoin is being used for. I think one of the best ways determine whether the bitcoin economy will continue growing is to consider the number of bitcoin transactions taking place. They continue to grow, and have been growing fairly steady since bitcoin was first used. See this link from Blockchain.com for a graph showing the number of bitcoin transactions over time. Bitcoin is not going away, it will change, other crypto currencies will continue to be released.
