What is the minimum amount needed to invest in order to join the sale?
There is no minimum amount in pre sale, the maximum purchase amount is 1000 ETH.
So i can invest even $1 if i want?
You can, but what exactly will you get out of it? If you just want to support the project than this won't do much, If you want to make a profit than 1 dollar will not make you much money in the end. This is not really the lottery, if you want to get something out of it you have to give much more.
A lot of people ask for this minimal amount because they get a kick out of participating - which is great! And if you add up a lot of small amounts you can really get that soft/hard cap together and meanwhile get a lot of possible users interested in the platform. But if you really believe in the project then you should think a bit bigger.
As someone already said,KYC costs money so i doubt they will allow those kind of investments.Also dont forget about the cost of token transaction.
and let us know what you think.
The only thing I have in common with medicine is that I get sick. I would freak myself out if I started going through it.
