with a value of $ 10K is indeed not a small value if used for investment, but if you invest in bitcoin, you will only get 0.32 BTC.
but if it's on another coin it's clear you will get more, but I really agree to do a good analysis before placing it.
because if you want to analyze at CMC, there will be lots of altcoins that are very potential and worthy of investment [besides XRP and ADA], but I prefer to invest in just a few coins to make it easier to control them.
if you want it to be easier, in my opinion, just investing in bitcoin is even more profitable and very reliable, and remember that the upgrade period is not far off.
I remember there was a time where BTC stayed at $10k for a long time. If only OP have this amount and ask this question before, then maybe BTC is going to be his first choice because it will easily gave him 1 BTC in exchange for his money.
Time flies so fast and BTC reach more price levels and as you said, our $10k amount can only gave us that 0.32 BTC but I think that was still better than having more than 1 piece of other crypto. They are only good for displaying in our wallet but the small quantity of BTC is still the one that will gave us a massive profit. In between XRP and ADA, ADA must be better although indeed there are better coins out there than ADA.
