no one can limit crypto, that's true because since the beginning of bitcoin's launch, many governments of a country have prohibited their citizens from investing and mining bitcoin, but it turns out that bitcoin has survived and is getting more expensive. this is proof that crypto cannot be limited.
I agree that crypto cannot be destroyed by governments because crypto operates on a blockchain, and a blockchain is decentralized and belongs to everyone. Attempts to attack BTC have been around for a long time but have been unsuccessful because no one has enough economic power to compromise BTC's security.
However, governments still have enough power to hinder the development of crypto, as exemplified by the governments of China and Nigeria. When investors fear legal implications associated with crypto, they will opt for safer assets, and the market's liquidity will be severely damaged.
The government can only limit the development of crypto projects like in China and Nigeria, but they can't stop crypto from circulating in their country unless they shut down the internet. Crypto will continue to run and many people will invest in it. So we don't need to worry about that.
Indeed, as crypto is decentralized in its nature, you can say that it is almost impossible to stop it altogether. Governments can try to ban projects in their countries but if internet is still available then people can use cryptos through international sources. Nevertheless, they also see that high levels of legislation can still have the effect of making the landscape of cryptocurrencies even smaller. For instance, while the Chinese can still buy digital assets, many prominent trading platforms have either relocated themselves or shut down all together, which means, instant access is no longer a thing.
Even if it is possible to use crypto, the legal status sometimes discourages the population to invest in it. As some of the users have pointed out, others may be concerned with the risks which arise from the legal framework or the possibility of access blocking as was the case in Nigeria. Therefore, even if we know that crypto will keep on running we must always watch out for new regulations and must always be willing to work under current conditions. But don’t lay back too much because business and technology environment is very competitive.
