That's what I'm doing even if I'm married since I regret for not saving bitcoin before while the price is so cheap and don't want this to happen again. Bitcoin right now had so big potential that's why its really good for us to save some for future. Bitcoin future is so good since it already reach on mainstream so I expect that more adoption will happen on it and this halving event would bring a lot of exposure to bitcoin especially if a lot of people see some outstanding price growth of this coin.
But if they can't afford to buy some amount because they think investing or trading it is more convenient to them then I guess what's more ideal there is to separate some part of their profit intended for long term hodl so that they may have some amount to use in future especially if they aim a huge success in future.
Saving some Bitcoin for the long term can be a wise decision especially considering its increasing mainstream adoption and the potential impact of the halving event. Separating a portion of your profits for longterm hodling is a good strategy to ensure you have some funds available for future success.
For that I have some money and I have already invested in Bitcoin and now I am using DCA method and I have decided to hold Bitcoin for more than 5 years. And I am sure that After 5 years I will be in profit because I believe in Bitcoin and in myself too.
For doubting people about the future of bitcoin maybe its best for them to track back the history and those amazing pumps happen thru years of its existence. For sure they will find it amazing then would provably get convince to hold since bitcoin really put some amazing numbers each years pass so provably we can see more from it. We can consider the level of adoption also the awareness happening on it so there's really big chance that more to come especially for countries potentially to declare it as their legal tender.
That's why same with other slowly accumulating to save on future I also doing the same since I don't want those past to happen again where I or many people regret not to have bitcoin at that time since if they just hold it for sure they gain a lot of money from it if they convert on last ATH happen or even at the current price of bitcoin.
For now I'm saving for hodl but there's a chance that I will also do DCA since wanna experiment for my self it can give me more better result.
