In as much as one believes in the existence of Bitcoin and as a coin worth investing prioritizing profits maximization over time without considering that things could go side ways can also be bad, irrespective of the fact that every business or investment is built on profits maximization, there can be loss too, tomorrow they said is pregnant and filled with uncertainty being ready to accept that there can be loss too and even considering what the worst situation could be not just looking at the profit side of it.
You shouldn't have that mindset if your intentions for Bitcoin is for holding because in as much as we may not really know what will be the exact worth of Bitcoin in the future but one thing we no is that you will never regret investing on Bitcoin because the future is bright and very transparent to easily see the possibilities, so perhaps I would advise you to remove your mindset on other alternatives that you feel could easily fetch you profit because you could get into a trouble with your investment, secondly I disagree with you on the aspect you feel that things could go sideways on Bitcoin, truly it may likely go sideways if your intentions are for short term profit making but however if your intentions are for holding Bitcoin for a long term I'm very confident that your investment will never go sideways because any price movement or volatility will not be your concern because your focus is the future and not current price fluctuations, so actually one of the most determining factor to your Bitcoin investment success is the ability to hold.
I hope he gets clearified on having the wrong insight of Bitcoin, let me believe Bitcoin is still at the very beginning of becoming much more acceptable and useful, many people are still going to believe in Bitcoin and take the bold step to invest in it. Over the past years, the rate at which Bitcoin was accepted was much smaller compared to today, Bitcoin is now accepted by companies and countries, this shows in few years from now Bitcoin will worth a lot in the market because of the demand will be high. So, we are left with a much greater opportunity in one way or the other to begin hold Bitcoin.
