Currently, I don't think that any coin can pop up in future that will take over dominance from bitcoin because bitcoin has already achieved a milestone that no digital currency have achieved one-tenth of it. Don't forget that it's because of the problem that bitcoin is solving that is leading to its adoption due to her decentralized nature and censorship resistance. After bitcoin was created every other coin that was created after bitcoin was unable have that uniqueness of bitcoin because they are centralized and the dev created these shitcoins to scam people from their hard earned money through pump and dump.
I gree with you on this, because currently I don see me too don't see any shitcoin pumping in the future that will take over dominance from bitcoin, normally I see other shitcoins as coin's that is just getting started, while bitcoin has already achieved a milestone that no digital currency have achieved even one tenth of it. Bitcoin is Very unique and the reason for mass adoption of bitcoin is because people see bitcoin as a safe heaven for storing wealth. Bitcoin security is the security you can strust, bitcoin is bringing the world together, only the benefits of bitcoin to the global economy is enough reason for you believe that bitcoin remains the king.
I think this always holds investors back from investing. If we were trading, we would have to observe the changes in the market perfectly. And we would always have to wait for a correct entry point, but since we are investing in a long-term plan, there is no need for perfect entry all the time, but if we invest step by step after starting the investment, the price will already be in agreement. Those who always wait for the market to go from a good level to a very bad level, that is, when the market dumps, they start investing, which does not always happen. When such investors wait and see the market going higher, they get more disappointed and at that time they think that now the market may have touched its highest value and if they invest now, they may face a loss in the investment, they do not invest even thinking that. After so much scrutiny, it is seen that they are sitting with their money but their investment plan is not being implemented. We do not need to plan like that, we should invest and increase the continuity of that investment and keep the investment for a certain period of time.
