Bitcoin is safe coin so far and whenever we talk about risk so our mean is to invest in new or meme coins which rise and drop chances are much high. we 1000$ become 10000$ in some days or drop to 100$. At once I remembered that these mentioned coins were considered high profitable coins.
I wouldn't advice people that get into meme coins or the new ones. IF we're talking about how risky investing to bitcoin based on its volatility, these are more of those.
The newer ones are very highly volatile because they get a lot of pump and dump. While the meme coins, they're also a lot of it and you're unsure if they're the best to invest with.
In the end, both of them are high risk and could do pump and dump so if you're into those and you're making, get that profit as early as you can because it's not guaranteed the next day as the market could drop fast with those.
