No need to buy a whole BTC.

You can get 1 mBTC if you want for $2.50

If you are going into altcoin at least read the home page and white paper.

I do like sia and grid coin.

If you do find a pyramid/Ponzi if they are honest about it, and you are aware you are gabling, have fun.

Ripple and dash are also questionable.

Along with anything you can find on coinmarketcap.com with a *** or **** (not mineable, or pre-mined)
