In Islam, the concept of wasting money or being frivolous with wealth is discouraged. While physical coins have a tangible value and can be used for charitable purposes, virtual currency does not have the same physical presence. However, the principle of not being wasteful with wealth still applies. Therefore, throwing virtual currency, especially in a manner that is disrespectful or wasteful, would likely be considered haram. It is important to be mindful of how we use and treat our wealth, whether it is physical or virtual. **

In most countries, it is not forbidden to hoard currency in the form of coins. However, hoarding large amounts of coins may raise suspicion and could potentially be seen as an attempt to avoid taxes or engage in illegal activities.

It's always best to check the specific laws and regulations in your country regarding currency hoarding. **
