Yes, I do not doubt the bitcoin will reach 100k for the next 5 years. The strong bitcoin and popular bitcoin will enable the bitcoin to reach 100k, and holding bitcoin up to 100k will be a very good advantage.
Even though am tempted to believe that Bitcoin will hit $100k in five years time, looking at the performance this year will make this thought a wide dream. However, fingers are crossed as we watch... No matter what the price is, I will always have some BTC in my portfolio.
