Wait for XMR to crash and buy the dip, then wait for the next pump and you'll double your money.
i don't think xmr would rise much again like before, it will like ethereum after the price spike high then would play at same range price.
yeah no problem to invest in XMR or other altcoin but you should know that investing in altcoin is a risky thing. do not hold your altcoin too long because it will be at risk and do not allocate too much on investment altcoin. you have to set it up and have a plan with it
Investing is always having a risk if you won't get a risk for your amount. please, keep them in your wallet and if you keep them in your wallet is not closing the possibilities you will get risk for your amount caused by your mistake.
