I think the next big boom will be at the end of 2021. Based on the math below that led me to a 6 month doubling time.

7/17/2010 BTC USD price $0.05
2/23/2018 BTC USD price $10,000

91 Months/2,730 days. 6 Month doubling time
(BTC doubles every 6 months, 2 times every year)

2018 = $40,000
2019 = $160,000
2020 = $640,000
2021 = $2,560,000
2022 = $10,240,000
2023 = $40,960,000
2024 = $163,840,000

These numbers are hard to believe, but remember all fiat is unlimited. Take a look at the TRILLION dollar notes in Zimbabwe and Venezuela. A single bill worth TRILLIONS of dollars. $2.5M in USD fiat is nothing. Bitcoin is unlike anything we've ever seen and I'm extremely excited!
