wt* btc

what is features of btc ????
the man who bought 1 week before 18k usd and now 12k wow great

So much ignorance...

So, think of bitcoin as the foundation of all other cryptos. Without bitcoin, there wouldn't have been an Ethereum, Ripple, Bitcoin Cash, etc. Bitcoin created the cryptocurrency boom that we're all hearing about on the news today.

Don't think of it as needing to have ~$18k to invest into one full bitcoin. You can start with as little as $20 depending on what exchange you use, and you can purchase fractions of bitcoin, eth, or other cryptos, to trade for other crypto currencies / ico's.

TL;DR: I wouldn't be where I am today if it weren't for bitcoin.

i will give it one more shot but its really disappoint me

Your best shot is to go for Bitcoin, You can start off really small and depending on what you do you can purchase fractions of certain cryptocurrencies, A mining rig is probably the best way to get money at the moment.
