I have been holding Bitcoin weekly, because holding Bitcoin weekly is the most important and effective than holding Bitcoin DCA monthly. However, the more holding can be done in the DCA method, the more important it is for a Bitcoin holder to have an emergency fund. If there is an emergency fund, any danger can be faced at any time and it does not affect Bitcoin holding. Every investor should know this and keep an emergency fund.
Your statement is not completely correct because even if you adopt the DCA, everyone may have a difference between the purchase of Bitcoin, as someone purchases it on a weekly basis and some buy a monthly basis. You can never emphasize that purchase of Bitcoin is much more important or effective than purchasing Bitcoin on a monthly basis. If you think so, it may also seem that buying Bitcoin can be much more important or effective every day. In fact, when purchasing Bitcoin, everyone has to pay the withdraw fee, so if you purchase Bitcoin daily, the transaction fee will increase, the transaction fee will be slightly lower than the purchase of a weekly on a weekly basis, and the transaction fee will be slightly lower than the monthly basis. Still, it may be dependent on the investor because if he has a good money, he can buy when he wants.
