. For example, if the price of Bitcoin increases in the market, then all cryptocurrencies in the market increase in price.
This is very misleading mate. This very statement is wrong about bitcoin market with the altcoins. Just because bitcoin rises doesn't mean other shitcoins would follow in same direction and start rising. If it were so then a lot of shitcoins patronizers would have made some tones of fortunes.
A lot of times this is what some persons assumes (which is a very retarding way of thinking) therefore opting to gamble their money in shitcoins/memecoins in the hopes that when bitcoin price rises their shitcoins would also do X times and put them in huge profit than when they have to invest such funds into bitcoin investment which they know to be a very sure future value adding asset.
You are right, the fact that other cryptocurrency depend on Bitcoin doesn't mean they are to be invested on ( trusted), Bitcoin drives them no doubt but they don't have same potential as Bitcoin and they can never have same potential because Bitcoin has proven itself. Bitcoin can rise and drop down to some certain value or price but most of these cryptocurrency rise and drop down to nothing, anyone who don't know or understand this will always make mistake to go and invest in shitcoins.
Investment is what takes time to manifest a good profit, and that's the exact characteristics we can find with bitcoin as digital asset. People that puts their money in shitcoins are actually not investing but dabbling with their money for quick returns that are some kind of a mirage, because most often these shitcoins dumps and never pick up again.
A friend was chatting me this morning about a particular coin she bought with #30k and afterwards the coin dumps leaving her with #400 and everything since it has not made a leap up. That's how shitcoins operates. Whether bitcoin rises or not they stay static and dump instead of pumping back after dumping.
For bitcoin as you invest using DCA, it affords you time to prepare towards your next buying time, no pressure, just consistency and making sure to buy whether price dips or high because that's how to stay consistent as along term bitcoin investor who wishes to stockpile much bitcoin in his portfolio for the next few years. Better than gambling on shitcoins out of greed for quick profits.
Your words are very realistic for new entrepreneurs. The way you have highlighted the difference between investing in Bitcoin and cold coins for us newbies seems easy and attractive, but often gets damaged to a large extent due to long-term losses. Your friend's story is a real example, for newbies it is a lesson that only the price will encourage growth but no one will rescue you when it falls. In this case, if you can maintain its continuity with a very good strategy, are mentally prepared to face risks, then do not panic about the price falling or rising and stay steadfast in long-term investment. The most important thing is that Bitcoin has been used as an established digital currency that is working as an alternative means of storing value. So I would say that you should be patient in investing and be rewarded.
