I have been using a Ledger Bitcoin Wallet https://www.ledger.com/coin/wallet/bitcoin for many year now and I am pretty happy with it.

Overall, I recommend to use a hardware wallet/cold wallet for holding your Bitcoin for the following reasons:

1. Have complete control and ownership of your Bitcoin.
2. Store your private keys offline. This significantly enhances the security of your Bitcoin holdings.
3. Immunity to malware attacks since transactions are signed within the device itself, even if your computer is infected, your Bitcoin remains safe.

I think Google allowing advertising for ETF bitcoin is a huge step forward for the cryptocurrency market. It provides mainstream exposure and legitimacy to Bitcoin as an investment vehicle. This move could potentially attract more institutional investors and retail traders into the market, driving up demand and consequently the price of Bitcoin. However, investors should still exercise caution and do their own research before investing in any Bitcoin ETF, as the cryptocurrency market can be volatile and unpredictable. Overall, I see this as a positive development for the adoption and acceptance of Bitcoin in the traditional financial world.

Dollar-cost averaging (DCA) is considered a prudent strategy for investing in Bitcoin because it involves consistently buying a fixed amount of Bitcoin at regular intervals, regardless of its price fluctuations.
This approach helps mitigate the impact of short-term market volatility, reducing the risk of making poor investment decisions based on short-term price movements. DCA allows investors to spread their purchases over time, potentially capturing both highs and lows in the market, and it aligns with the long-term potential of Bitcoin as an asset class.

By doing DCA, you'll not even have to think about the "best time to buy Bitcoin is around the time of Bitcoin Halving: April 22, 2024" 

Now, what are your predictions for seeing one of these BTC commercials at the next Super Bowl? 

Congratulations and welcome the bitcoin holder family!

Binance is giving interesting APR through launchpad when you hold BNB in the platform so it can be interesting to have a small % of your portfolio.
To be honest, it's what I do.

I would recommend you to have most of your Bitcoin on a self custody wallet. So to be the closest to 100% on a wallet.

But I you want to do some trade some time, you can have 10% on exchanges.

What happen to FTX last year is a good example of why you should not have much BTC on exchanges but mainly have the self custody of your Bitcoin.
