Yes, it must be discussed so that we can know about them, what is their ability and if they grow well, what benefit will we get. This will also increase our knowledge but some people want to understand everything from Bitcoin only because they think that Bitcoin is the only coin that will succeed. Their thinking is also correct, but only until other coins can grow themselves. But in the future, no one knows, maybe a coin will grow so much that it will also reduce Bitcoin. This work is also a bit difficult so many intelligent boys become weak in understanding while working in it.
Discussing about shitcoins or other coin apart from bitcoin in this thread is never necessary our focus here is about bitcoin and no other coin for it is bitcoin that has a great potentials to invest on as long as your investment plan is a for a longer period of time puting your money on any other coin aside bitcoin could be very risky and you may regret at last while you choose to put your money into it, if you even choose to do so let me be 10% of your income, invest in bitcoin for a longer time and have your peace of mind.
Different people have different strategies in terms of investment and everybody have a particular strategy that work for them.
Buying Bitcoin by DCA does not necessary mean that the investor have limited capital, most people that buy Bitcoin by DCA still have the capital for lump sum but one of the reason why some people prefer DCA to lump sum is that some people see lump sum as a method that is risky because of the volatile nature of Bitcoin which they cannot possible tell what the price may be in the future. So to avoid any uncertainty in regard to dip they see DCA as precautionary way of buying Bitcoin than lump sum which requires buying Bitcoin at once with the capital at hand without considering whether the price will dip or not.
If your investment plan is for a longer time there is no need been afraid of market votality it is only when your investment plan is for a short time purpose that will be afraid to invest using the lump sum strategy, there is nothing wrong using the lump sum strategy if the money is there to do so because it will help to increase your Bitcoin stack more faster because your are accumulating Bitcoin with huge amount of money, if you even started bitcoin investment and you decide to lump sum at first before adopting the DCA strategy good since you have a long time investment plan but the reason why the DCA strategy is more adopted by investors is that it gives your room to accumulate more Bitcoin gradually either weekly or monthly without always thinking of the price of Bitcoin and HODL so I don't see any reason seeing lump sum strategy as a risky one when choosing bitcoin long term investment.
