this is the right time to buy polka dots, why delay if this is a golden opportunity?, you can see the truth through the chart,
because the highest price of DOT was at $54 and now DOT is only at $6, of course this is a good opportunity to invest in DOT.
yes even though the OP said people staking on DOT have reached 50% more I think it will have no effect on the price of DOT,
and maybe if there is another decline there will be $3 and I believe $3 is a very strong bottom.
People are not entirely sure if it is the golden chance to buy it right now, it would be a bit weird if you felt so comfortable about it and tell people about how comfortable you are by investing right now. Obviously, altcoins are a bit riskier than bitcoin, which means that they could end up being not so high and that would be understandable as well.
I personally would suggest you to buy it as soon as you can, because you really believe in it, but if others do not then I would understand it as well. It is not an easy decision to invest into anything, doesn't matter what it is, and people grow with the idea that there isn't free money anywhere, so it is hard to accept the fact that it is a good looking project.
