Since my predictions in the price of Bitcoin, i haven't limited its cap to a specific price, my reason because i see Bitcoin as an investment for profits and progressive in each cycle, if investors rate their investment return within a specific interval, that doesn't limit what profits it will generate, it can go beyond or stay lesser.
No body in quote can cap Bitcoin price exactly, it has to be on basis of speculation within a specific period and as long Bitcoin utility continues, the price of Bitcoin will always make new ATH. Bitcoin price is speculative not definite.
