Honestly, if you're going to be trading with this amount of money on a platform that isn't going to be working I'd recommend just going to another one that is going to actual work, such as GDAX, which even though it's run by Coinbase is actually a nice trading system with a good amount of volume.
Wouldn't wait until they release a new engine with new problems, it's just not worth it.
Whatever anybody does, please stay away from Coinbase. The IRS has their sights pointed at them. We will be going through another drama once the IRS goes on a full attack maybe later this year. Coinbase says they will fight the case in court but I am skeptical they have the money to fight it full on
It is not just about Coinbase
That is true but it is Coinbase that is being "harrassed" by the a department of the US government right now. Whatever you say, the advice of staying away from Coinbase is more right than wrong since you are risking having your Bitcoins locked.
The amount of your coins kept in Coinbase is not the issue here. The issue is the fact that Coinbase could be closed down sooner than we think.
It is still better to cry in Mercedes than on a bus
It this case, losing a few satoshis is less painful than losing a few bitcoins (this is just to give you an idea of the scale, all numbers are fictional). We should remain realists, using web wallets is very convenient and it more often than not outweighs all that rhetoric about anti-Bitcoin nature of these wallets. You don't have to make sure that your computer is well protected from all kinds of threats lest your coins get stolen (for most ordinary people that is next to impossible, let's be honest here as well). And then comes the question of fees which may be a decisive factor, especially if you transact on a pretty regular basis
For you maybe. But remember a lot more people are using Coinbase. In some cases it is what they use as their main wallet because it is connected with the bank they use. And it is for that reason why I always advice the people who are new to Bitcoin to STAY AWAY from Coinbase. Sooner or later they will be locked down be the US government if they do not give in to their demands.
