I would put half of that on BTC, the current valuation makes it a very good play in my humble opinion. Could it go down? Sure, but I'm also convinced the king of cryptocurrencies, the first mover has a lot of runway to go.

The other half I would divide between the following cryptos:

Litecoin (nowhere near the ATH atm)
Ethereum (The upcoming changes should make this one to watch)
Monero (a personal favorite)
EOS (the hype means it still has room to go)
ADA (Cardano is undervalued atm to me)
