I don't know if anyone has suggested the DCA strategy to you, but that's so far the best accumulation strategy, especially for newbies who are enthusiastic about HODLing.
The DCA technique involves regularly buying smaller amounts or any amount that you feel comfortable with, at an interval you're also comfortable with, could be weekly, or monthly, depending on your income flow.
This process is just like saving money in a piggy bank regularly for a future purpose.
This method helps to ride out the short-term impacts of the market's fluctuation and make you feel less tensed about the market movement because you're buying at different market conditions and hoping to HODL for the long-term.
