I have 100k, would like to invest in cryptocurrency.

How about other cryptos like Ripple xrp or dogecoin..where do i buy them from
Speaking of XRP. I have dozens of those things na zinaact weird sana. Zilidouble in value sometime this week na zikarudi back down in a few hours. Halafu sasa naskia in a few months, either nitakuwa na enough dough to build a homegym or be left with dozens of coins worth 0.0000USD. It's a weird feel.
