Hahaha Facts
If you invested $10,000 in $XRP on 1 January 2018
Today you’d still have $10,000

In other words you would have been better off storing your $$$ in your bank account which would have given you some interest and $10k in 6 years would have given you 2-3 grands if I'm not mistaken

Here is another Fact.
If you had invested your bitcoins in XRP (which is what most altcoin investors do) you would be in a massive loss today because on 1 January 2018 XRP was worth 0.00020000
BTC and today it is worth 0.00002000
BTC which is 1/10
In other words 10 BTC invested in XRP on 1 January 2018 is worth only 1BTC today.
