Well if I am to be ask, ill be prefer for half of your savings so that you will not regret if theirs anything happens or trouble, me as a full member I've experienced investing half of my savings I can say that trading is just a matter of how you deal with. If you want to earn bigger than you've invest so better deal with the right person or a rights coin so that time to time you can evaluate if it is the time to trade some of your coin.
