Say you had as an example 50k usd in bitcoin, how would you invest it in a serious way to grow your wealth long term? Would you hold in coins, P2P lending etc or rather would you cash it and buy company shares or something?
Quite a substantial amount of money. I will not trust myself to handle or invest that amount of money. The safest maybe is to buy and hold bitcoin, sell when it has a bit of profit and repeat the process. If you can take risk, you can invest them on some gambling sites that accepts investor.
