Yeah, knowing and understanding the right strategy and method that suits your investment is really important and that's why many people be it newbie or even veterans in investment failed at some point in seeing that their Bitcoin investment becomes successful. There are so many things that could go wrong if the investor doesn't know or choose to follow the wrong advice just as this person is portraying right here and it's important we guide and correct this. DCA method is actually the best and most convenient method as it's involves less to do other than just dividing your income and using the part that you can actually spare to continually buy Bitcoin and also it's important too to have a tangible job at that because as an investor there are certain criteria that you must be ready for like keeping up extra funds for some uncertain events that won't warrant you messing with your investment like emergency funds and etc.
It takes good skills and knowledge to become a wise Investor. The right strategies and techniques tend to bring perfect results and this includes the application of an Investor in measuring their techniques or strategies in seeing market movements, DCA is a very effective technique in terms of Investment especially we say Bitcoin asset Investment, but many new users do not understand this old strategy.
In Bitcoin investment we have only three strategy which are; lump sum or lump summing, buy Dip and DCA(dollar cost average), I list them here because you are sounding like a trader when you mentioned that strategies and techniques because in Bitcoin investment we don't need techniques or strategies to measure anything or check the market movement these you mentioned are what traders uses to make profit not investors. Investors are concerned on accumulating and holding Bitcoin for a period of time and hoping to see their investment do great in the future and again it doesn't take good skill and knowledge to become a wise investor but rather it takes understanding, discipline and patient to become a great investor and I will suggest you don't use the word wise investor because everyone is wise in their own way(s).
Every Bitcoin investor should aim to hold Bitcoin for the long term. Buying bitcoin regularly and patiently holding it for the long term is a best investing strategy. And the best way for this is DCA. Investing wisely doesn't always mean technical knowledge, but investing regularly in a disciplined manner, holding patiently for long periods of time, and making the right decisions at the right time, That is investing wisely. Everyone is wise in their own way and in their own strategy, and that personal right perspective is what makes an investor a successful investor.
