Just many exchanges are asking a lot of money for the listing. And if you want to invest in technology, then you are doing it in vain, as long as you keep the tokens of any project, a strong competitor can come out, and your project will never be in demand. Better buy a bitcoin.
I agree with your opinion, invest in bitcoin. The reason is very simple, of the hundreds of types of coins that are currently not close to the price of bitcoin, even 10% of the price of bitcoin currently does not yet exist.
This proves that people who like to trade crypto prefer bitcoin investment, because bitcoin has been able to prove a very expensive coin in 2017 for USD 20000, and proves that many people become millionaires. Such momentum makes people believe in bitcoin.
