No one should invest more that they can lose. That is the base rule for any investment. If you are putting your last money in any investment or depriving yourself from any basic need, that is more gamble than it's an investment. Plus, as said many times before, this is a marathon, not a sprint and you can not expect an easy money with any serious investment. My advice to anyone having extra cash to spare is to invest. For the others, make more money to buy more coins
