though i'd not advise people to expect their money to double/triple, of course it can obviously happen, but that could make them expect too much and prolly fall under pressure in the short term if Bitcoin isn't do well at that time.
Sure!, You're right but if they can stomach the volatility of Bitcoin and zoom out , because the volatility is really what is going to bring them under pressure within this time period /years of waiting on sideline, hence focus on the future price of Bitcoin in that minimum 4 years time period and with halving cycle backing it up, it's historical in the data that the price of Bitcoin have repeatedly surged even more than the double or triple in the price I made mention.
