A simple scroll through coinmarketcap right now would show you 99/100 cryptos have seen an increase in value in the last 7 days and it is not some small increase (were talking doubling and tripling in prices)
Just look:
Those are just the first few coins as well! I mean even look at steem and steem dollar right now! They are both reaching highs
I think this is crazy! I do not see why you would want to buy coins at these high prices, I would wait for the big fall that is coming soon to buy bitcoin or any other altcoin!
Also if you have steem dollar exchange it for steem now because it may be a while till we get this good of an exchange again. Although prices could keep going higher there is a big crash coming afterwards
