Might be that its just legitime transactions but am pretty worried they're not, I hope someone here can explain this.

take this example: https://blockchain.info/block/000000000000000000357c11562377eb7882e0f282674147dd7affeef0f82762

"Unable to decode output address"  Why?

Where do those huge amounts of btc suddenly come from?

Most recent transactions of 10-20k BTC. or another recent one with 37,418.47242639 BTC: https://blockchain.info/block/00000000000000000009237e27163013276a36cad2ecf623abfe7de84b10d04d

It doesn't look like regular transactions to me, can anyone advise?

Blockchain block cannot be change as the blockchain network info is stored everywhere. If you did changed it successfully but when you send it, it won't get validated as each blocks thatbsre newly created is based on it's parents block that has information from the block header.

of course, for us blockchain is also good and safe we hold now, because the development of krypto prices every day is also increasing, so I think we also believe that its future will also be better.

That's the point of block chain -> security. It's much easier to forge a note than even try forging Blockchain database
