Yes you are right, people investing in shitcoins have there reasons why they choose to invest on it, one of the reasons I have mentioned, now about the growth believe is true they believe Bitcoin is slow in growth and some also believe Bitcoin will not grow more than this.
Now the reason they believe feel or reason this way is because they really do not understand what Bitcoin is, they don't have the knowledge about Bitcoin they feel is just like other cryptocurrency, some people even feel those shitcoins they are investing into will one day grow in price more than Bitcoin.
But I will advise before going into shitcoins please ask people that has gone into it and stopped they will be the ones to tell you the real truth about it, ask like 6 people and from there you can make your decision or no that truly shitcoins should be avoided totally.
Well not all altcoins are shitcoins. Some of them has the potential to grow and people are still making profits by investing in them. So I will not say that altcoins are bad. Only the professionals who have deep knowledge about the market and its movement can make profit out of altcoins. Believe me or not, altcoins are all about trends and hype. Once it fades away, it is gone.
As long as it is not bitcoin, it is shitcoin because they are same with gambling and they are not classified as an investment because if you hold them for long, you will be a failure for doing that. This is how those shitcoins dev decieves people that their shitcoin will gradually grow like bitcoin and have a high value just to make you invest in them and in not time you will be rug pulled. You are new to this forum and I will not blame you for what you said above because you are those set of people who think shitcoins can give you quick profit.
As long as it is a centralized coins, it can be manipulated because a back door can be made anytime. Bitcoin is for the future because it will last and that is why it is the best to invest in because it has great potentials to give you profit in the long run and it will save your funds from depreciation because bitcoin is a store of value. A lot of shitcoins have crashed and it is useless to buy them.
You don't need to be a professional to invest or bitcoin or have deep knowledge of the market before you can invest in bitcoin as a newbie, all you need to do is to figure out the right amount that you can use to buy bitcoin consistently and persistently and continuously for you to get started as long as you will hodli for a long time.
Have you considered coins like ethereum, Bitcoin is the best but we can't dispute the fact that ethereum coin are also good and has been for years, let be honest here if given ethereum to hold would you have fear in you.
I understand your point since those coins are centralized there's every opportunity for it to be tempered with and there by leading to it fall and that is why Bitcoin is the best crypto currency in the world to invest with.
However we can't say any coin that is created and made decentralized is a good option or can we, so I think there's more to a coin being a good option for investment and for me long good credit history is one.
