if you invest in Bitcoin for a long time, then if it is from 4 to 10, then it will bring success
Holding bitcoin to or 4 to 10yrs doesn't necessarily mean that our investment is going to be successful or in profit. If we look at bitcoin past record it shows that long term holders have been more successful than short term holder , however since the future is unpredictable. There are so many things or factors that may affect the performance of bitcoin. Holding bitcoin for long term may reduce the impact of short term volatility, however it doesn't mean that it has removed the chances of loss.
If hodling bitcoin for 4 to 10 years won't be profitable, then I wonder what will be profitable. You can compare the price of bitcoin now and 4 -10 years ago and to think about those who have been investing bitcoin and accumulating and hodling bitcoin till this moment, do you mean such hodling is not a successful one? Ofcourse the duration of this investment is longterm and longterm investment like this is which investors are encouraged to take part.
There is still risk in long term investment, so holding for longer time isn't a guarantee that our investment is going to be successful
Except it is not bitcoin, maybe shitcoins or except one is a careless investor.
