Goodmorning,
You have to pay close attention to Bitcoin and the products you want to authorize (ETF).
Most bitcoins (and other cryptocurrencies) are in the hands of a few exchanges that every day manipulate the market to speculate on projects and tokens that directly and indirectly manage.
This is the bitcoin rich list, you can see that the first 20 bitcoin owners are exchange and have most of the bitcoins in circulation:

Many exchanges use "false dollars" to pump the price of bitcoins and other coins (theter !!!)
In addition, the processing of transaction data is carried out by a few centralized entities that can decide what, how much and how to move everything at any time, these are called miner, the biggest miner in the world is called https://www.bitmain.com (there have been many problems in the past and the risks are very high).
BEFORE AUTHORIZING ANY PRODUCT YOU NEED TO RESOLVE MANY PROBLEMS THAT ARE ON THE BACKGROUND.
PLEASE, DO NOT BECOME CAUSE OF A TRAGEDY!
Best regards,
Vincenzo Muggeo
