This brings my mind down to bitcoin and its growth because since I knew bitcoin it was worth noting, then I had no positive knowledge about bitcoin, now bitcoin has a staggering $95K market value and it is growing nonstop everyday it brings me to the point of realizing my mistakes of not acquiring as much bitcoin as I could, the time no one including myself didn't believe satoshi will become the lord of the highest coin in the coin technology, this is a tittle from me though
If you look at the Bitcoin after 5 years you may regret again incase you don't start accumulate Bitcoin nowadays. So regretting about the past won't change the future, rather starting accumulation would decide our future. We are witness to how Bitcoin has been growing, including institutional interest in it. Countries are adapting Bitcoin even considering Bitcoin as a reserve asset. So more growth on the way, we just have to know capitalize it.
Better strategy would accumulate through DCA strategy. So you can take advantage of the each dump and you will have more Bitcoin on your bag. That means you will not have to regret it after years, and you will have good savings in old age. Until how long you can hold it's depends on you, but keep in mind that Bitcoin for life, not for the lifetime.
