antiddos_fun(source_system, antiddos.sec = getOption("Rbitcoin.antiddos.sec",
  10), antiddos.verbose = getOption("Rbitcoin.antiddos.verbose", 0),
  verbose = getOption("Rbitcoin.verbose", 0))

`source_system`	character, a unique name of source system, could be any name `c('kraken','bitstamp','blockchain','alt_bitstamp')`
`antiddos.sec`	numeric time in seconds between API calls on the particular source system, defeault `getOption("Rbitcoin.antiddos.sec",10)`.
`antiddos.verbose`	integer, Rbitcoin antiddos verbose message. Should be used when user prefer `verbose=0` but still wants to see antiddos waiting time.
`verbose`	integer. Rbitcoin processing messages, print to console if `verbose > 0`, each subfunction reduce `verbose` by 1. If missing then `getOption("Rbitcoin.verbose",0)` is used.

The following options can control antiddos process:

getOption("Rbitcoin.antiddos",TRUE)
getOption("Rbitcoin.antiddos.sec",10) seconds to wait between calls to the same system
getOption("Rbitcoin.antiddos.fun",antiddos_fun) - custom antiddos function. Default the one documentated on this site.

numeric time of wait in seconds.

Environment of name Rbitcoin.last_api_call which holds the timestamps of last api call per source_system during the R session.

Rbitcoin built-in antiddos function handle only api calls launched within the current R session. By default it will wait getOption("Rbitcoin.antiddos.sec",10) seconds between calls to the same system. It cache the api calls in Rbitcoin.last_api_call environment object in current workspace. User can provide own custom antiddos function using getOption("Rbitcoin.antiddos.fun",antiddos_fun). This way it is possible to cache last api call in own data storage (like database), this can allow concurrent R sessions + queueing to be handled by the antiddos process. Custom antiddos should return numeric value of time spent on antiddos waiting in seconds.
