Before thinking of investing in any sector what one considers is how long you are willing to hold. Let's take the history down to how investment all began. Moving from the era of Real estate to stocks to metals to oil blocks and now digital assets we would agree those who made it big in all this investment options were those who had the patience to hold.
These assets dont need to be held for more than 5-8years. Of course you can do that too and you will appreciate the rise in value but you could possibly make more by selling it at a certain time and buying more such assets. Stocks might be the only exception to this, they give dividends and you will probably not sell but only buy more.
Why though? I am not saying that you "have to" hold it for 5-8 years, but holding it for that long is also not a bad idea neither. I personally have been holding for nearly 2 years now and I am going to hold for another 8 years for sure. This doesn't mean that I do not want to have anything else, I will add in more and more investments and maybe some of them will be quicker and some of them could be long term.
This shows that if you want to get in, and make some profit and get out then that is fine however, at the same time you could get in and wait for 10 years and get out as well. Both of them are quite valid ways of approaching investment if you ask me.
