I think Bitcoin is a secure network because it offers a transparent and reliable system. The blockchain is also decentralized, which means that there is no central authority that governs Bitcoin and that the system is open to everyone. I also think that there is therefore no risk of falsification of transactions because the Bitcoin blockchain is immutable. I think the minimum amount to invest in Bitcoin usually depends on the exchange or the trading platform, as well as the payment method used and your location.

I also think that the price of Bitcoin often experiences big sudden price rises and falls that you can take advantage of. Currently below the psychological level of $ 10,000, many traders find it an interesting level to take advantage of the next upside that could take BTC / USD to its annual highs around $ 13,000.
