It's always best to invest in Bitcoin.
I mean Bitcoin has yet to be in it's best figure, If you're aware of the circulating speculations in crypto space today, they are eyeing a $100k in 2021. That might have a chance to happen as speculations can influence market sentiments.
Take it for example those who bought Bitcoin at $1,000 while Btc was still $1,100, we never thought Btc could reach $20k in a span of 1 year. If you buy today at $11,000 who knows Btc will be $100k the next day. Though it's better to buy at a lower entry point, but we also don't know If Btc will have another dip. It's better to at least secure fragments while Btc are still considered affordable.
