please write this command

You can use the following command:

spendzerocoin <amount> <mintchange> <minimizechange> <security level> <address>

• amount = Amount to spend.
• mintchange = Input true if you want to re-mint any leftover change, input false if not.
• minimizechange = Input true if you want to minimize returning change, input false if not.
• security level = Amount of checkpoints to add to the accumulator. We have been recommending a value of 42 for this, but you can increase it to 100 max. Note that the more checkpoints there are, the longer the minting process takes.
• address = If basecoin address, funds will arrive in basecoin. If stealth address, funds will arrive in CT.

To simplify, we recommend the following:

spendzerocoin <amount> false true 42 <address>

Projects developed on blockchain technologies will certainly be very popular in the near future. Well done boys! Good luck!

Staking still a bit bumpy , but they will get there eventually 

New Veil wallet release : 1.0.1.4

- Quicker recognition of orphans and forks.
- Denomination filter when using spendzerocoin rpc. Allows the user to specify a specific zerocoin denomination to spend with. For example if someone wants to 10 denoms into 100's they would want to apply a 10 filter.
- Stake miner will not stall if it is "close enough" to the chain tip.
- Reduce stake miner's tendency to produce redundant stakes.

New wallet still shows some orphans but at last I got some stakes again.

whats the different between bv and sv wallet
my veil was in basecoin
if i wanna send some to exchanger did i need to swap to mint zero coin?

edit
help i cant connect to my wallet
any node or something?

Basecoin Veil addresses start with "bv". Stealth Veil addresses start with "sv". Your Veil being in Basecoin means it is in a Basecoin address. Right now the two currently available exchanges require Basecoin Veil addresses, which you can generate in Settings> Advanced Options> Console tab> enter: getnewbasecoinaddress

About connect to your wallet, do you mean you are having trouble finding peers? If so you may have to update your wallet. Please make sure you have the latest wallet here: https://github.com/Veil-Project/veil/releases

When typing in the consode gives an error: Try to spend with a higher security level to include more coins (code -4)
What could be the problem?

Is the Discord even more active then the telegram channel? I might pop in to check. At least in discord you can find the things you are looking for because it's more organized.
