Investments are open to everyone. There are no restrictions. All that is needed for this is to have a minimum balance in your personal wallet, allowing you to open a contract.
In order to open a contract, there is no need to transfer your tokens - all coins are on your personal wallet, outside Voyager platform. It's safer, isn't it? To activate the contract in account, you only need to link your wallet with the necessary balance. It's simple.
This is very tempting for me. Perhaps I should think about the decision to invest in this way in Voyager project.
It all depends on what means you have. If you have a cryptocurrency, then yes it is worth now to invest in good projects. If you have only fiat, I would not advise buying cryptography now
