That's right, bitcoin is indeed very volatile and very risky. For that, if you want to invest in crypto, either bitcoin or altcoin, you need a deep understanding, so we are not wrong in taking action. I do not recommend investing before someone really understands what investment is and what is crypto . So investing in crypto is not for trial, so if only just try it, the risk is loss.
Not only knowledge, but we also need to be emotionally and financially prepared, as crypto is volatile, so we should figure out our purpose, if it is for short term or long term as we don't know and we can't predict the price of Bitcoin and other altcoins. So just invest when you are ready enough, don't just invest because you think today has a low price, whenever know the dip of it.
