For this reason anyone that is interested on becoming an investor should consider the very real possibility that not only things will not go according to their plans, but they may even lose money despite picking one, if not the best asset in existence today, and once you realize this your overall strategy and preparedness will improve, however we cannot be rigid about the way we think about our plans as sometimes a complete overhaul may be necessary.
I don't want to sound overly optimistic that you can never loose your money in your investment but if you aren't playing out either in trying to sell too soon to buy back or trying altcoin as a means to become less stiff in your investment, the chance of losing in your Bitcoin investment is actually very slim if you're doing the right thing. And I bet you aren't referring to market correction as loss and feel that at such point in time that things aren't going as planned.
I don't see any easy possibility of taking any losses, aside from act of carelessness and just as you mentioned (playing out either in trying to sell too soon to buy back or trying altcoin as a means to become less stiff in your investment). Bitcoin is a safe assets to invest into, if the future is yet unknown but then history holds how Bitcoin has moved from so low to a crazy all time high, now also would serve as a history to the future only to those who seized the opportunity of accumulating now and hold instead of relying on doubting the outcome of the market, whether profitable or not.
The only reason why they lose on holding if they buy the news then get panic with it. But if they are fine even if there's fud spreading then continue to accumulate while everyone is panicking with such condition occur in the market then provably they are pretty much fine and no lose will happen. if there's a decline in value then that's just a paper loss and bitcoin ratio still the same with their accumulated asset. Bitcoin is really a safe asset to choose compare on other alts since for many times we see it having a great recovery after it experience a bearish run. That's scenarios should be considered by those who doubt about doing holding since they should consider those great recoveries and bull runs scenario since for sure they will be fine on holding investment rather than thinking about short term then trade those shitcoins around since they provably be more in losing side with choosing that option.
