Not much. If it just so happens that a certain platform you sent your funds to asks you about where the funds came from, just say you bought it P2P. Though this rarely happens as far as I know. As long as buying P2P is not illegal where you're from.
[Not necessarily. But in my opinion, one should have alternative like other secured investments. Recently, I came across Mallconomy, the future Metaverse with lots of earning opportunities. If you want to know more you are welcome to ask.]
