Bitcoin is the best decision to invest in, but anywhere else you choose to invest is at your own risk. But if you have invested in bitcoins yet, don't face people, because we are currently aiming to improve. Even if you collect most aggressively during this time you won't encounter any juice because you can sell most of your claims by holding bitcoins for only one year.
That's because bitcoin is liquid at a top coin so, anyone can sell at any moment they wish to sell it. And ETH is also a good choice, a top 2 coin that has a lot of use case and other projects that have been using its smart contract.
