If you count the number of coins and tokens that are dead now, there are thousands of them.
That is not just the problem, the problem is that many coins are just not increasing. They will increase, later fall and not get to all time high again. They are not assets of value but assets of gambling.
Bitcoin is very different because it is an asset if value.
I agree with you; other coins look like gambling because of their nature and their value. Bitcoin will always be the first whenever they are talking about coins because it is far different from other coins. You cannot buy other coins and have peace of mind when holding them, but when it comes to Bitcoin, you can hold your Bitcoin without thinking about the market like other coins. Bitcoin has more value than any other coin; that is why it remains the favourite coin that people use to trust and invest their life savings in.
Bitcoin has already killed other coins since the day people realised that Bitcoin is not just an investment; Bitcoin is another way of changing lives. It will be difficult to see someone holding Bitcoin and still be panicked unless the person just started investing, but when it comes to other coins, you can never trust them because you don’t know what the price will be; you can wake up one day and be regretting why you invested in them.
