The usual cautionary notes on exchanges:

1. Only use them to buy or exchange small amounts of coin. Never leave any coin on an exchange since you don't actually own it.
2. Move coins to your personal wallet immediately after buying them.
3. Never deposit large amounts of coin on an exchange - if you want to buy $5k USD worth of something, do it $1k or less at a time.

This minimizes the pain when, invariably, an exchange goes down.

This coin has great potential. Looking forward to big things in 2018!

Anyone can mine Bitcoin, you don't need to be Chinese. Just buy an ASICS rig. There is no premium for newly mined coins - most are quickly sold on an exchange for fiat.

Sexcoin (SXC) seems more appropriate - only $.25 a coin and faster confirms.

I think 10,000 is possible in 2018 if blockchain continues to take off. Both BTC and ETH could reach $1T in market capitalization which would be over 10k per ETH. For big profits though, look to more obscure coins like SXC that have the potential for 100x or 1000x expansion.

Bitcoin fees are still tiny when expressed in Bitcoin -- the problem is the dollar has crashed relative to BTC so all the poor saps holding dollars no longer have any buying power. Anyone who bought 10,000 BTC for a pizza back in 2011 isn't really sweating .01 BTC fees to move their coins around.

Sexcoin (SXC) has been on a wild run past 24 hours - up 85% or so and still just $.25 a coin. I like its chances.

Not a new coin but Sexcoin SXC is just on fire right now - up 85% past 24 hours on about $500k of volume and still only $.25 a coin. Lots to like - the adult industry needs a coin, it has good parameters, wallet is stable, and someone's clearly investing a lot into it.

Another good thing about SXC is the wallet actually works - mine found about 8 peers and synched up the blockchain in about 8 hours. So it's not like you are stuck keeping the coins on an exchange. I was going through all my old wallets a while back and found some SXC that I had mined and was pleasantly surprised to see that the coin was not only alive but actually doing fairly well in this broader rally.

Sexcoin, SXC, has just been on fire the past 24 hours. +50%. It's on exchanges, has pretty good parameters, and has a name that's going to attract a lot of investors once they see it. $.18 or so now and I think it's going to $100+. Strap in for the ride while still cheap. Trades over on livecoin.net.

Why on earth would banks need or want Ripple? They can already exchange funds easily using existing centralized networks -- blockchain is useless in that context.

Ripple is trash - it has an intrinsic value of $0 per coin and is only powered higher by fools who, apparently, want to donate money to the company behind it. I'd rather keep my money but if you really want to donate your net worth to someone, there are better causes than XRP.

Sexcoin (SXC). $.14 today, $100 within a year.

Yes - it has become like URL's in the early days of the internet. Things like feathercoin and sexcoin which were dead for awhile will come back because they are on some exchanges and the name is interesting.

Houston we have liftoff! Time to get SXC again.

No, it's a bubble. Stick with Ethereum over Cardano.

Sexcoin (SXC) looks pretty good. Still just $.14 but has been surging like crazy of late.

Look no further than Sexcoin SXC. Surged out of nowhere to get back up to $.14 and a nice $172M market cap and could shoot a lot higher.

Looks like sexcoin is back - $.14 and climbing. The next LTC?

Bitcoin is essentially a safe that is impenetrable and that has a combination so complex that all the computers in the world working from now until the end of time couldn't by chance guess one.

But if you give someone your combination, then all that security is worthless. They'll just open the safe and take your money.
