I have a hard time believing this story that you have sold the house for crypto investment. But if you did, my opinion would be to invest at least one part in Bitcoin. (40%)
For the most part it worked out
free online picture upload woaahh haha, selling house to invest in crypto without assurance is crazy, if i were you i will just hold still to the coins you have, that coins have a great team and have a strong community to support it prices, you are certified risk taker.
Agree with you that we should not invest our money in anything when you are not sure about its future. Altcoin are good market now so we can but it easily you better try to buy it without selling your house as bitcoin is good coin which has highest potential and it's best coins to give you enough earning for getting new house very soon.
