Do not attempt it and I would advise you to ignore any pm you might receive concerning this else there is possibility of you getting scammed.
You just said the fact, am sure lots of people will start sending personal messages to the OP just to assist him by growing his bitcoin, but the OP should just be careful because he is going to be scammed, the might send so links to the OP to ask him to send his bitcoin to the website, or they might send him some wallet to send his bitcoin their so that they can help him grow it. Am just making assumption but their are other methods which can be used to scam so what I will recommend to the Op is just to ignore any message he received, anybody trying to make suggestion will do that on this thread and nobody will send him personal message.
If you keep your bitcoins in a gambling place you will definitely lose. Because gambling is like that, it will either come or it will go.
Some people do claim they are a professional gambler so they are always confident that they are not going to lose when gamble, but we all know that when gambling their is no assurance that we are going to win that’s why if you are gambling you shouldn’t have confident that you will always win, because when you start losing you won’t want to give up because you will have the believe that you are going to win back all the money that you lose. I don’t see gambling as a source of growing money and that what some people don’t understand, gambling should just be done for fun and don’t think you can make money from gambling because you will end up losing everything you have.
Most of the time there is a high probability of going. If you want to grow your bitcoins you must hold for a long time.
I don’t know if their is other methods but the best method that you can use to grow your bitcoin is just by holding it, just purchase your bitcoin and you can just abandon it in your non custodial wallet address, but make sure you properly secure the wallet private key, make sure it’s store in a place where their is no internet connection. You can carve your private key on a iron steel and sure it where nobody can have access to it. Carving private key on a iron steel is very secure because it can’t be destroyed by either water or fire, so incase if their is fire accident or water accident, then your private key is still secure.
