The process for buying Safemoon in the U.S. is broadly the same as anywhere else. The main thing is to get Binance tokens into a wallet. Then, you can use a Defi application (like PancakeSwap) to buy your Safemoon tokens.

Otherwise, few people will be interested in this Safemoon. This means low demand, and that's how Safemoon's coin value will crumble.

Subscriber growth is harder to track than the other metrics. Only the current subscriber count is displayed for a particular subreddit, and historical data cannot be rebuilt retrospectively as subscribers do not have a visible historical imprint. A third-party website, RedditMetrics (http://redditmetrics.com/), has been retrieving and storing real-time subscriber counts; however their data on the particular subreddits of interest only reaches back to 2012 so the subscriber growth analysis can only start at this point. Fig 2 shows the three social media metric time series for each cryptocurrency; note that subscriber growth is the only metric that can have negative associated values, caused by more users unsubscribing than subscribing on a particular day.
