If you plan to hold BTC for the long term or until it is 100k usd, you may want to think over the choice of the wallet you claim you are going to use, if you want to hold BTC for the long period, it should not be in a hot wallet, i would advice you invest in a hardware wallet for the best security, or set up a wallet like electrum on an airgapped device and operate it offline in a safe enviroment. Do not hold your BTC in wallets or apps of centralized services and exchanges.
Security is something you should not save on, it is better to buy a hardware wallet once and be sure that your funds are safe. Exchanges are good for buying coins, probably for today it remains the most profitable way.
But for long-term storage, this is not the best option. There are many examples and the recent FTХ shows how dangerous this is. Those who think that they will have time to quickly withdraw their funds if something like this happens are mistaken. No need to repeat the mistakes of others, no need to lose money in order to learn this lesson.
