Bitcoin prediction has made many people missed calculate it at any given point in time. Base on your investment, already bought 1BTC, when was 17k, which was bought before the last Bull Run market, before it makes all time high (ATH) of 60k plus and you didn't sell, at least half of Bitcoin as of then and currently 1BTC is within 29k to 30k still in profits, while next Bitcoin many people are predicting 100k, base on that I'm very sure Bitcoin price will be more than 100k per 1BTC in the next bull run market.
