BTC has a MC bigger than all the other cryptos combined. Lmao, you literally have zero clue what you are talking about.
Bigger does not imply automatically more safe or more chance to survive.
Remember Lehmann Brothers?
Watch what is now still going on with Deutsche Bank (which is even bigger than Lehmann Brothers was).
Remember 2018 when BTC crashed 80%? Much worse than 2008.
