DCA never gets old and it's the strategy that the majority of us is aware of. What we need to plan is to get on how long we're going to hold the bitcoins you've bought. If you have no exit plan, that's just fine and you can get some portion of it when you want to and sell it at your will if you need some extra cash for some purposes that you need to spend it.
DCA will be the most used method especially that majority of us can't buy bitcoins in bulk then people will go use this strategy since they can buy their bitcoins on regular intervals depends on when they can afford to do it. I think planning to sell well depends on situation and the needs of the holder itself since if he feel that he need to cashout something then they must sell their profits nothing can stop them or tell that its wrong since that's profit already they can earn that back since your balance left will still generate you a profit and also you can do your interval accumulation once you are ready again to accumulate.
That's it, while the major institutions can do whatever they can and are able to buy in bulk and thousands of bitcoin. We as simple investors can do little by buying through DCA. And if you're onto the point that you want to sell, the matter is on how you are satisfied for your time of selling. But as you can see, many from the forum don't want to sell as soon as possible and there are more prolonged plans that they'd sell at the right time with a better pricing and no one knows when that time is going to come. As soon as you're wanting to cash out and you're happy with the price and that's how you reward yourself then do it.
All will matter on our capabilities and knowledge on doing something like this to make our plans works and we actually don't need to have a lot of money to became a holder since at first place any amount will do ang it will continue to grow once we are ready to accumulate and make those DCA strategy we use work according to our plan. Also we can't compare ourselves to those institutions since they have a lot of money to invest. And since we are small fish in the game then its better to use our brains to maximize our possible chance to earn, For sure there's a lot more to learn especially if we talk to those people who have same interest with us like what we or other people discuss on this thread. For sure a lot of people know something that can truly help to make their hodl plan to happen.
