yes it doesn't matter how small we start our bitcoin investment , the most important thing is being consistent in our investing in bitcoin and also being patient to hold for a long term without being moved to sell due to market sentiment or trends. bitcoin doesn't profit those that lack patience and are desperate. As long as we have discretionary income to start with, with the DCA strategy starting with any amount won't be an issue.
We have already read stories of many people who have regularly used a portion of their monthly salary to buy Bitcoin for the past few years. They are now able to keep a good amount of money in Bitcoin and accumulate Bitcoin, from which they have already been able to make quite a good profit due to the rise of Bitcoin in the past year.
Therefore, instead of giving too much importance to the current Bitcoin price, they should invest a portion of their salary in Bitcoin every month, so that even if the Bitcoin price goes down, it will not affect them. DCA would definitely be the right strategy for them to accumulate Bitcoin.
