Bitcoin is super DE-centralized, and a bulletproof store of value (for long term HODLers, not silly day traders.)

Many other cryptos ARE centralized, though (like ETH), so be careful out there.

ETH could be destroyed fairly easily, even though it is the premier development platform (not currency.)

It is almost inconceivable that BTC could be wiped out, though.

Only a cabal of trillionaires could summon the necessary computing power to make a 51% attack on BTC. Even if such a cabal existed, they are probably benefiting from it, so it's a vanishingly unlikely scenario.
