As per the current market situation, many good coins are falling down because of some reasons like the XRP, TRX and there are many others. I will suggest buying the XRP, TRX, and such coins in the amount of at least 10k, and soon those coins will return a high-profit margin.
If you had said that 3 days ago I would partially understand you, but not with the part with XRP, that's not the best advice.
In my opinion you could make a lot of money with XRP trade, provided the judge decides in favour of XRP on February 22nd.
But the other way around you can also lose a lot.
This is not only risky, it is gambling and in no way suitable as long-term advice.
Be quick on February 22nd if you really want to have XRP and the courts decide positively about coin, but buy the deep. Many will also sell on the day because the gamblers have bought in beforehand.
The same happened in January 2018 when there were rumours about Coinbase and XRP, but this time XRP can drop really low.
What you can do now is to buy a small or larger portion of XRP, with the money you don't need for life, and sell it the day before the judicial decision.
Nobody can guarantee you that until then, February 22nd, the price will not go down any further and the hoped for profits will not be profits at all.
That's why I don't believe in a long term strategy for XRP right now, TRX is less risky.
And as you wrote before, there are many other coins, but that's another topic
