(4) I know I made this thread specifically for bitcoin but how can you be a good investor if you don't expand your horizon. It's advisable to try out other Altcoins I'd recommend ethereum or ripple. Don't put all your eggs in one basket always research to see which coins are thriving well, check out their past and possible future, ask questions this is where those your sources come in.
In other words just try and choose your assets wisely.
Um, wut? Both ETH and XRP are absolute shitcoins. Don't do that at all.
Put all of your eggs in the Bitcoin basket and thank me in 10 years. It's the only asset worth holding well into the future.
