Our thought?
You have been suggested on the first page that you need to buy a hardware wallet if you are intended to hold your coin in the long run. We know that Trustwallet is an open-source wallet but it does not mean you will trust them, it is better to input on a hardware wallet or paper wallet but I will not suggest this wallet if you don't have experience creating this --technically error was the most problem when using this wallet that will perhaps a result of losing your coin. Ledger and Trezor wallet would be a good choice.
