Bittrex will prevent trading on 3 2 coins for US clients on June 22nd in 1:00 UTC. US clients can still maintain these coins inside their Bittrex pockets, they just may ‘t trade them on Bittrex. 
Luckily, almost every coin that Bittrex is delisting / “Geo blocking ” can be traded on DEXs like Bancor, on other non-US exchanges like Binance, or in cases on other US exchanges like Coinbase (DNT for example trades on Coinbase).
UPDATE: Bancor is also restricting US customers. Still, my point is the similarly: Ethereum-based coins can be traded on a wide array of DEXs on the Ethereum Network.
UPDATE: Bittrex announced more restricted coins, see an updated list of restricted coins.
Also, although it doesn’t help US clients, these coins may be traded Bittrex International.
This means US clients don’t have to do everything (they can just store their coins on Bittrex as long as they remain listed on Bittrex International), but if they want to trade a coin after June 22nd, they will need to move their coins off of Bittrex and onto another exchange.
Of course, this also means these coins have a risk of their cost decreasing and are likely to see somewhat lower trading volume moving forward, so do think about how this impacts you.
Lastly, remember, crypto marketplaces are global marketplaces and Bittrex geoblocking US customers as a measure of precaution isn’t a comprehension alone to depart a coin (particularly in the event that you’ve got additional options). Bittrex is really a US market and can be probable looking for extra hard to stay in compliance in regards to US clients.
