I have a few disagreements If your going to get 3 gold get it with a stone pickaxe. If you want to have a lot more rushes get way more gold. Also you can mine the nexus, hide with spy and mine it some more it works better that way.
Mining gold with a stone pickaxe can also be done but if u want to be quick u can use an iron pick Getting a lot more gold is a good idea but if u don't have an e chest then where are u going to store all that gold? I don't think that gold can be stored in the top of the furnace After mining the nexus and hiding in the nexus is a bad idea because there are some people who comes swinging like crazy and can find u. for example: say u hit the nexus 4 or 5 times and u went invis and some guy found u.so u only did some damage whereas hitting the nexus continuously will get it down more quickly
If your getting 3 gold getting a stone pickaxe is way faster. Because smelting iron takes a lot of time. When I spy rush I get about 18 gold, go and smelt then get 18 more and smelt. I spy rush that takes a while because I can mine the nex then hide. Also if you have echest you can put your gold in there. Also you have to hide good, it's not very hard nobody can find me usually. Sorry I don't have a YT channel.
