if you have 12 btc its up to you if you want to gamble it but for me investing your 12 bitcoins when the value is too low is make sense because maybe it will doubled if you invest in a low price and then sell it whenn it pump so my advise is if you get money try to build a business so you should need to take the risk in crypptocurrency or hold it for a long time so you will see the value in the future of you coins.
