Even bitcoin is not safe because our wallet is hackable of we are not careful in this cryptocurrency world. I think we have to just invest money that we don't need in near future because if we stake our money that we need for daily needs we'll have a bad time because we will always look at the market and that habbit will make us panic and lost our investment. So, the best way to invest in crypto is having a mindset of nothing to lose, so we'll be safe in terms of mind.
