You choose a good coin to investment.
but your action of selling you house is too very risk and look very improper
Right, because basically investing is not required to sell assets that already exist, let alone those assets are the homes where we live, unless we have many other home reserves.
Its best to only invest what we can afford to lose and selling the house where we live is quite risky regardless how profitble the investment is. But I admire his guts for taking such actions, it only means he has a big trust to crypto investment.
Whatever coins you invest in, make sure you know everything about it especially you allocate huge amount for each coin.
