$10,000 here is a huge amount if you decide to invest. So let's take a closer look at the topic of XRP and ADA tokens. But in my opinion, you want to invest for the long term, so you can invest in bitcoin and you will probably be safe with it. Since we research and invest, even if the profit is small, we can definitely see the face of the profit, so we will not suffer a big loss.
I agree with you that with a capital of $10k it is better to invest in bitcoin especially if the investment is long term. Investing in bitcoin is not only safe, it is also profitable, especially with a capital of $10k at current prices, at least you can get around 0.37 BTC. If later the price of bitcoin rises dramatically and even sets a new ATH record, it is likely that with a capital of $10k, you will get almost 2x profits.
Now if we can invest in this market of bitcoin it will be very profitable for us in the future. But for that we have to follow some rules to invest later. If we invest in bitcoin now then we have to wait for a long time. If we don't wait for a long time. I can't make profit from here. We always have to keep in mind that when the Bitcoin market has a bad situation, we have to buy and hold Bitcoin and sell it when the market is good.
