Defining a large amount of Bitcoin can vary depending on individual wealth, location, and background.
Many consider a large amount of BTC to be valued at $10,000 or more, with some saying anything above $100,000.
It's recommended that Bitcoin comprises 5% to 20% of your entire investment capital, with 5% being safe and 20% considered risky.
Buying large amounts of Bitcoins can be done through exchanges and OTC broker platforms, but it's essential to be prepared and start with smaller investments if you're inexperienced.
