Hello I think Polkadot will make huge waves in the market and to prove this I invested 70% in $PCX (Chainx).
This is a coin that will make the bridge between Polkadot and BTC and Between Kusama and BTC.

When Polkadot takes of the need for this bridge will be massive and these guys already patented the technology. I believe this will be a top 20 coin easily.
They also give 40% staking rewards.

This coin went up a bit but with a market cap of only 40Mio this has the potential to do an easy 10X.
There is also an Airdrop planned next month for the Sherpa X tokens and they will win the auction for the Parachain of DOT and KUSAMA.
