Python Script to Transfer SBD to Exchange 通过程序来减少到交易所转帐出错的可能

When transferring your SBD assets to exchange, you have to fill in the correct memo otherwise your money is likely to get lost.

A few months ago, I accidentally transfered 100 SBD to @blocktrades but luckily a few hours later I got the refund.

You don't get lucky everytime. Therefore I think it is less likely for things to go wrong if this can be done automatically via scripts.

I have written a Python script based on Steem-Python library and it works quite well for me.

from steem import Steem
from steem.account import Account
from keys import account_akey
from nodes import steem_nodes

id = 'justyy'
wif = {
  "active": account_akey[id]
}

steem = Steem(nodes = steem_nodes, keys = wif)  
account = Account(id, steemd_instance=steem)
balance = account.balances 
x = float(balance['total']['SBD'])
print("@" + id + " has " + str(x) + " SBD")

if x >= 40:
  y = 30
  print("transfering " + str(y) + " SBD from @" + id + " to @bittrex")
  steem.transfer("bittrex", amount = y, asset = 'SBD', memo = "The MEMO key required by your exchange", account = id)

Let the script run once per hour via crontab. When account balance is larger than 40 SBD, automatically it transfers 30 to your exchange account.

Advantages:

Saves your time.
Can't get wrong.
Makes you feel that your are actually earning something on SteemIt.

You don't need to use Python, you can also use steem-js as long as you put in the correct MEMO.

虽然现在在STEEMIT上转帐到交易所的时候如果没有填写 MEMO，是会提示的，但是有时候你手快，可能把你的帐号地址给复制过去然后就点发送了，这时候就悲剧了。

很久之前，我误操作100 SBD到 @blocktrades 就是把MEMO填成帐号地址了，幸运的是通过各方途径联系了官方，几个小时内收到了退款。

但是别的交易所，如 bittrex 可能就不是这么的幸运了，转帐转错了有时候权当捐款了。

是不是每次转帐的时候都提心吊胆，生怕转没了？其实你只要懂一点程序，完全可以通过程序的方式来转帐，程序只要调通了第一次，之后再执行出错的可能性几乎没有了。

比如，我的自动转帐脚本如下（Python）

from steem import Steem
from steem.account import Account
from keys import account_akey
from nodes import steem_nodes

id = 'justyy'
wif = {
  "active": account_akey[id]
}

steem = Steem(nodes = steem_nodes, keys = wif)  
account = Account(id, steemd_instance=steem)
balance = account.balances 
x = float(balance['total']['SBD'])
print("@" + id + " has " + str(x) + " SBD")

if x >= 40:
  y = 30
  print("transfering " + str(y) + " SBD from @" + id + " to @bittrex")
  steem.transfer("bittrex", amount = y, asset = 'SBD', memo = "您的交易所要求的MEMO KEY", account = id)

把这个脚本放在 crontab 里，一小时执行一次，那么当帐号SBD大于40的时候，自动转 30到交易所。留下10块钱是为了够银行发利息。

运行了好几天，很爽，这样的好处是：
