Investing in Cryptocurrencies is not for the faint-hearted. Altcoins (any coin other than Bitcoin) are very volatile and could swing 5-10% every day for days together. So, if you are uncomfortable with that kind of volatility, Shiba Inu is not appropriate for you.
Some of the best-performing cryptocurrencies in 2022 were very differentiated from the rest. That aside, Shiba Inu was not a fully differentiated cryptocurrency at the time of launch. While it is differentiating itself now, that is still a work in progress. If SHIB fails to differentiate itself sufficiently, new investors are likely to invest in cryptos that quite different from the others.
